[Y/n] and Haru sat between Daisuke and Suzue in a traditional Japanese home in front of Daisuke's grandmother. "I am Kikudo, his grandmother." She said. 

"My name is Kato Haru." Haru said as he bowed.

"My name is Thomas [Y/n]." She hated how her name sounded in Japanese.

"Haru-san. [Y/n]-san." Kikudo said, "Such wonderful names. Thank you both for taking care of Daisuke."

"Um, well..."

"This is a souvenir from Hong Kong." Suzue said.

"Is that so? Why don't we all enjoy it together then?"

[Y/n] smiled a bit, remembering their time in China. [Y/n] spent most of her time with Daisuke and in his room. Think what you will. [Y/n] had a great time. Suzue served the moon cakes while Kikudo made some tea. "Daisuke, how are things at your new workplace?"

"Nothing...noteworthy."

"Here you go." Kikudo gave Haru and [Y/n] their drinks. "He's grown up somewhat selfish, so hasn't he been causing you trouble?" She asked.

"Oh no, Daisuke has helped us in many different ways. Thank you for the tea." Haru said and took a sip of his drink, "However, there is somewhat of a difference in financial viewpoints compared to our coworkers. It often creates chaos on the scene."

Daisuke glared in Haru's direction. "Daisuke!" His grandmother called.

"Yes."

"You must always refrain from actions that would trouble people at the workplace." Kikudo scolded.

"Yes." 

For some odd reason, [Y/n] found it kind of cute that Daisuke was being scolded by his grandmother.

"Haru-san, [Y/n]-san, pardon my asking, but what are your ages?"

"Well, I'll be 30 this year." Haru said.

"I just turned 27." [Y/n] said.

"Not only job-wise, but also as a senior in life, please do coach Daisuke well." Kikudo said to Haru and bowed to him.

"Please leave it to me!" Haru said, "So he could become a true policeman, I will coach him with everything I have!" Daisuke glared at him.

"Daisuke!"

"I look forward to your coaching. Thank you very much." Daisuke said as he bowed to Haru. They heard footsteps from outside, and their butler stopped walking then bowed. "This is our butler, Hattori." Kikudo said.

"Pleased to make your acquaintance." He said.

"The pleasure's mine." Haru said as he bowed. 

[Y/n] bowed as well. "Mine as well." She said. 

"Please excuse my attire." Hattori said and left.

"As you can see, he is rather unsociable and meddles in the garden all the time. I wonder if that's acceptable a butler." Kikudo said. 

"Butler? Is that the one you always talk to?" Haru asked, and [Y/n] placed her hand on the earring in her left ear. After that mission with Umezu, [Y/n] found out the earring that Daisuke inserted his AI butler in was the most earring in the world. It alone cost ¥4,439,253,000.00 ($42 million).

"Kato-sama, that is the AI butler. It is called HEUSC." Suzue said.

"AI? Huh?"

"Artificial Intelligence." [Y/n] said with a deadpanned look. 

"Oh, [Y/n]-san. What a lovely accent you have. Where are you from?" Kikudo asked, and [Y/n] smiled. It was nice that her future in-law took an interest in her. "I was born in Bordeaux, France then I moved to Paris when I was thirteen." [Y/n] said.

"Really now?" Kikudo said, and [Y/n] nodded, "You seem like a sweet girl, right Daisuke."

[Y/n] blushed a bit. 'She trying to set us up...? Is the universe on my side?' She thought. Daisuke smirked a bit and glanced at [Y/n]. 

"Yes." Daisuke agrees, and [Y/n] blushed more. 

"Ne me fais pas rougir, s'il vous plaît. Je ne veux pas m'embarrasser. (Don't make me blush, please. I don't want to embarrass myself.)" [Y/n]'s voice went up an octave as she stared down at her lap with a reddened face. Daisuke was rather amused by her reaction.

After meeting with Daisuke's grandmother, Haru and [Y/n] were being driven by Daisuke. "Elle m'aime bien, Elle m'aime bien, Elle m'aime bien...(She likes me, she likes me, she likes me...)" [Y/n] mumbled over and over with a silly smile on her face. She was really happy that Daisuke's grandmother liked her. 

"[Y/n] and I'll be off on a business trip to Nagoya tomorrow. Make sure to refrain from any actions that would trouble your coworkers." Haru said, and Daisuke hit the gas, Haru and [Y/n] deeper into their seats.

"Hey, don't start breaking the speed limit when I said that!"

"This is private property." Daisuke said.

"Elle m'aime bien..." [Y/n] muttered.

~

[Y/n] sighed as she scrolled through her Instagram. She constantly double-tapped on the screen liking all of the posts of her feed. Most of them we're of her friends and family back in France. Some of her friends were on vacations, others were out with family, a few of them recently got engaged or is starting a family. Even [Y/n]'s bitch sister was getting married. And, here [Y/n] was, miles away in Japan, single, childless, and most importantly living with a coworker because she was scared to live on her own.

Let's not forget obsessing over a man, who is giving her mixed signals. Sometimes he smiles at her and holds a conversation, but other times, he just blankly looks at her and says nothing. [Y/n] wasn't sure if Daisuke didn't know how to respond or he didn't care enough to, but...It was messing with her head.

[Y/n]'s eyes widened a bit while looking at her sister's engagement ring. It wasn't big, but it looked expensive. The last time [Y/n]'d talked to her sister, her sister was bragging about this important businessman that she was dating. He was from America if [Y/n] remember correctly.

[Y/n] just hoped and prayed that her sister didn't call her with her "excitement". [Y/n] was getting to the age where she'd want to be married. Maybe, one child on the way, and settled down in a happy home with a pet. [Y/n] couldn't think of anything more perfect than coming home and being greeted with a hug and a kiss. Cooking dinner together with her partner, going on trips together, dates, and spending long nights together.

[Y/n] blushed while thinking about doing all of those things with Daisuke. Then she sighed, realizing that she couldn't even get him to come out on a date with her in Hong Kong. At this point, [Y/n] wanted to throw her phone out of the window. 

The years of torment [Y/n]'s sister, Isabella, has put her through...[Y/n] was kind of jealous of her sister, and she hated it. Maybe, [Y/n] was feeling homesick, but more jealous of her sister than anything.

The train stopped, and [Y/n] and Haru stood up and collected their things. [Y/n] noticed Haru talking to the boy was sitting next to him. "Who was that child?" [Y/n] asked.

"I just met him on the train. He failed his entrance exam." Haru said while handing her a meat bun, and [Y/n] hummed. "Sad..." She muttered and took a bite. Suddenly an alarm sounded. [Y/n] stuffed the rest in her mouth.

"Attention, everyone. As of right now, we will be closing the shinkansen train platform. Please exit the platforms immediately. I repeat. As of right now, we will be closing the shinkansen train platform. Please exit the platforms immediately."

[Y/n] and Haru ran towards the office directed people out. "What's the matter?" Haru asked.

"I'm sorry, but could you please--"

"We're from the police." [Y/n] interrupted, showing her badge, and Haru showed his. [Y/n] tried not to cringe at her photo. Her look was mean, and she had a short pixie cut. God, she wanted to get this photo changed so bad.

"I heard there's a stand-off going on inside that train parked over there." The officer said, and Haru dropped his thing. "Look after this for me! Let's go, [Y/n]!" Haru said and started running. [Y/n] followed him.

Once they got to the train, Haru asked what was going on. "Well, apparently there's a stand-off happening with a young man in car 16 in the front." The officer said, and [Y/n] and Haru went in to negotiate with him.

"Don't come closer!" The kid yelled, causing the detectives to stop. He pointed the gun towards the hostage's head. 

[Y/n] began to scout the area. He had the door behind in locked shut with a bike lock, a camera in front of him, and a bag full of self-defensive tools, like pepper spray and a taser. "If you come any closer, I'll kill her!"

"Help me!"

Haru's eyes widened a bit. "Hey, it's me! You know, the one who sat next to you!"

"L-Like I know! I don't know who you are! Get out! Now!"

"Now, you should calm down." Haru said, and they turned then slowly walked out.

Once the door closed, Haru called Shinnosuke. "Hey Kamei, have you been getting any intel?" He said, and [Y/n] pulled out her phone, "No, [Y/n] and I are at the crime scene right now." Haru took [Y/n]'s phone, knowing exactly who she was going to call. "No! Don't tell him absolutely not!" [Y/n] glared and tried to take her phone back, but Haru held it out of her reach.

"Kato-san? [Y/n]-san?"

The officers from the First Division was already here. "That was fast." [Y/n] muttered. 

"Why are you two here?" Ryo asked. 

Haru shoved [Y/n]'s phone in his pocket and walked closer to Ryo. "We happened to be on this train. The perp is male. He said he failed college entrance so age is somewhere around 19 or 20. I'm guessing he's from around Hyogo." Haru explained.

Ryo's eyes widened a bit. "How do you know--"

"I was sitting next to him, until moments ago."

"Any other information?"

"No, I only started talking to him when we were close to getting off."

"Understood. We at the First Divison will be handling this case. Kato-san, [Y/n]-san, please take your leave." Ryo said.

"It's all right. I'm not a stranger in his light. Let me do it." Haru said.

"Do you have the authority to be on this crime scene?" Ryo asked.

"What do you mean?"

"Why don't you ask yourself that question?" Ryo said, and [Y/n] glared slightly. She knew what he was talking about. She remembered it like it was yesterday. When that guy tried to rob that bank...Haru was given permission to shoot the man in the arm, so he would drop his weapon. But, no one suspected that one of the clerks there would be working with the criminal. When she picked up the gun and pointed at Haru, he instinctively shot the woman, severely injuring her. After that Haru couldn't shoot a gun anymore without thinking of that woman, leading him to get demoted. But, much to his surprise [Y/n] was demoted as well.

"You were my first friend when I came to Japan. You did not make fun of my accent or got angry when I punched you in the face." [Y/n]'s translator app said as [Y/n]'s face redden a bit, "I do not really care about the money here, and the office was boring without you. And that strange man, who wanted to take me out, started bothering me again. What I am trying to say is you are like a big brother to me, and you are my best friend. I want to stay with you." Haru smiled at her words and ruffled her short hair. [Y/n] blushed harder and glared then jabbed him in the gut.

[Y/n] grinned at the memory then remembered that Haru had her phone. The [h/c] haired woman glared at the man walking in front of her. She kicked the back of his knee, making him fall to the ground. "What the--" [Y/n] reached into Haru's pocket and took her phone back.

"Merci." [Y/n] said with a smug look and stepped over him.

"You could have just asked." Haru growled while getting up.

"There a promo campaign on Chaintube, where you'll get 100 million coins for 10 million views." [Y/n] heard and looked at the two guys talking behind her. "You mean this? That has to be it."

"Are you working hard on your job, Inspector Kato, Inspector [Y/n]?" [Y/n] knew exactly who's voice that was, and her heart swelled with happiness when he called her by her first name.

And the view of him wasn't anything to complain about. Daisuke was dressed in his usual suit with his hair slicked back and his shades on. Haru looked at [Y/n], sighed realizing there was no use in asking her anything because she was too busy drooling over Daisuke. 

She may have snapped a secret photo of him, but that's not a conversation they wanted to have. They went outside to Daisuke's car. "Hurry up and get going." Haru said as they sat there. [Y/n] put on her sunglasses.

"This is precisely the time when I would like some coaching." Daisuke said, and [Y/n] grinned.

"Damn you!" Haru growled, and Daisuke sped off. "HESUC, play what's going on at the Investigation Headquarters." Daisuke said.

"...is in possession of firearm, and apparently there is one woman collapsed on the floor. It's very likely that she was killed by the perp."

"Any demands?"

"He still hasn't made any. There is suspicion that mental derangement may be involved. Position the SAT where they can target the perp."

"Roger."

[Y/n]'s eyes widened a bit. "Stop the car." Haru muttered, "I said, stop!"

Daisuke stopped the car. "He's not that kind of guy. He's not the type to kill people." Haru muttered.

"I have to agree. He's still young." [Y/n] said. Daisuke pressed a button on his steering wheel, something came out for under Haru's seat. "Hurry up and put it on." He said, and they got out.

Once their devices were on, Daisuke threw the hook, and it hooked onto a phone line. Daisuke smirked as he around his arm around [Y/n]'s waist, causing her to blush. "Let's go." He said, and they were lifted into the air. Once they landed, [Y/n] still stay snuggled again Daisuke.

Well, until they had to get Haru down because he got stuck on the line. Daisuke was rather annoyed by this. Once they made it to the train, the detectives had to come up with a plan. "What to do now?" Haru muttered while looking at the SAT team outside of the train, "The instant we go out there, we'll be the ones who'll be arrested."

"Set it to channel three." Daisuke said.

Haru set his watch while [Y/n] listened through her earring. "Enter car 16 as the negotiator, and lead the perp to the fourth set form the front."

"Roger that."

"Once te sniper gets a visual, shoot to kill."

'They're planning to kill the poor boy.' [Y/n] thought and glared slightly.

"Can you connect my voice with them?" Haru asked.

"Connect. Please go ahead." HEUSC responded.

"Chief Takei? Can you hear me?" Haru said.

"Haru?"

"Kato-san? How did you get on this line?"

"Why aren't you properly negotiating with him?"

"The man seems to be enjoying this situation. There's no room for negotiation." Ryo said.

"The guy I met wasn't like that." Haru said.

"You're still saying that? You have no right to be a police officer anymore."

"Haru, leave this case to us."

"Why don't you see for yourself what kind of man he is?" Ryo questioned, "He's streaming on ChainTube right now."

"Show me the applicable footage." Daisuke said, and the video streamed from his watch and was projected on the wall.

"Scared? Of course you're scared." The male said while pointing the gun closer to the woman's head, "But it's going well, so stick it out with me a bit longer, okay. All right, I'm bringing you the shinkansen stand-off as a live broadcast! Please spread the word."

"What the hell is he doing?" Haru questioned.

"This is a bad look for him." [Y/n] commented.

"HEUSC, give me information about the other passengers." Daisuke said.

"Understood." HEUSC said.

"I'm from the police. Let's talk it out." Ryo said, and [Y/n]'s eyes narrowed a bit when the male brought the gun closer to the camera. 

"It's fake." [Y/n] muttered as she pulled up her sunglasses.

"Huh?"

"The gun. It has that plastic hole thing under it." [Y/n] explained and pulled up a picture of a model gun then pointed part she was talking about. Then the camera pointed at a woman on the floor. "And look, the woman on the floor...most likely she fainted, but there is no bleeding anywhere."

"But, there no way of knowing for sure." Haru said, and [Y/n] glared. "I know what a fucking gun and a dead person looks like." [Y/n] grumbled.

"What should we do?" Haru muttered while looking out at the SAT team.

"What do you want to do?" Daisuke asked.

"What do I...?" Haru muttered, "I...I just don't want him to die!" 

[Y/n] smiled a bit, and Daisuke stood up. 'Oh god, he's about to do something cool.' [Y/n] thought with stars in her eyes.

Daisuke adjusted something on his watch and put on his sunglass. [Y/n] pulled hers back down and stood up. "Under current circumstances, the smoke will be effective for 8 minutes and 30 seconds. We'll finish everything within this timeframe." Daisuke said.

"Smoke? Finish everything? What do you-"

"Reimburse all damages at double the cost." Daisuke said to HEUSC. "Understood. Balance: Unlimited."

The smoke rockets came flying in the air and landed in front of the train. As soon as the smoke engulfed the SAT team, Daisuke, Haru, and [Y/n] went running through them to the front of the train. Daisuke carved through the glass in the front of the train.

They entered the train and could see Ryo and the male. "Kato, can you hear me?" Chief Takei asked.

"Yes."

"For some reason, there's a smokescreen up, and the sniper currently has no visual contact. I want you to shoot. I will take responsibility." Takei said, and [Y/n]'s look horrified as she looked at Haru.

He was seriously messed up after shooting that woman. [Y/n] didn't want to pull him out of an even deeper hole from shooting a guy who's barely starting a life of his own. Daisuke held a gun out to Haru.

Haru looked at [Y/n], who was giving him an intense almost pleading look. "Should I do it? Should I? This is a real performance!" The male yelled in English, and Haru's eyes widened. "HEUSC, can you access the perp's smartphone? I want to look at his emails." Haru said.

"Understood."

The perp's emails were projected on Hary's watch. "Haru, do what needs to be done. Let's work together once again." Takei said, and Haru's look darkened. Then he grabbed the gun. [Y/n] looked away as Daisuke kicked the door down. 

"Everyone, please calm done! Please stay where you are." Haru said.

"Don't come closer! I will really kill her."

"Would it make your little sister happy if you do something like this?" Haru said, and the perp's went wide with shock. 

"Why do you..."

"You want your little sister to have surgery in the United States, right? That's why you caused this incident, so you could get more views and get money from it." Haru further explained, and the perp glared.

"It's none of your business! I have to...I have to do this!"

"No, you don't." [Y/n] said, "Your little sister would have a brother who is in jail. She'll go months, maybe years without seeing you."

"Heave-ho! Heave-ho!" The old women on the train started to get angry, ready to attack the perp. "Don't come closer!" The perp yelled, "Don't you care about what happens to her?"

Ryo pulled out his gun and pointed it at the perp. "Stop it!"

"I don't care what happens to me! So please go to the farewell concert!" The hostage said while crying, causing the other women to cry. "We won't let your death go to waste!"

[Y/n] was a little confused at this point. "What is happening?" She muttered. The women got close to the perp when suddenly music started to play, causing all the women to rush to the window. Even the woman on the floor got up. The perp dropped his model gun and went to pick up the real gun that Ryo dropped.

"Stop it!" Haru pointed his gun at the perp. [Y/n] noticed Haru trembling. Daisuke slowly walked closer to the perp. "Don't come closer!" The perp yelled and pointed the gun at Daisuke. [Y/n] know the perp wouldn't shoot. If he had the intent to kill someone, he wouldn't have brought a model gun.

"You're under arrest for flagrant detention and bodily injury." Daisuke said.

"Just a little more...Just a little more, and I can send her to America..." The perp muttered.

"I'll make sure that your little sister gets her surgery." Daisuke said.

"How can you..." The perp slowly dropped the gun, and Daisuke took it away from him.

~~

"Can I ask you one thing?" Haru asked as he, Daisuke, and [Y/n] got into the car, "How did you know he wouldn't shoot you?"

"'He's not the type to kill people.' That's what you said." Daisuke said, and Haru's eyes widened a bit. [Y/n] smile grew. 'Is it possible to be more in love with this man?' [Y/n] thought, and Daisuke sped off down the street, making Haru scream and [Y/n] giggle with joy.
