Levi's team stood straight in front of Levi as he caressed his son's arms that was sleeping on his lap.

They were staying in the Reiss estate in the center of Nikko City. Krysta, a member of Levi team, told them that they could stay there since no one was residing in that estate. She and Ymir couldn't join the team as much as they want since Levi told them to focus on the restoration of the Reiss estate that was located in Kyushu.

Back to Levi Team, they were in the living room, standing straight across Levi, sweating and nervous.

Levi roamed his eyes around and felt satisfied how clean the place was. He then sipped his black tea and looked at them "Now tell me what the fuck were you doing when Xyril went missing?!" Levi asked irritably

"I was stopping Eren and Mikasa" Armin answered honestly

"I was trying to get Sasha and Connie back when they ran towards the barbecue restaurant" Jean followed, and the rest just lowered their head

"For now I will let this incident happen, and I will forget your fucking actions since because of this, I found (F/N). But if this happen again, you know what will happen, your response?!"

"Sir, yes sir!" They answered in chorus

"Uhm, heichou," Eren took a deep breath and curiously asked "That was really (F/N)-san?"

"Yeah"

"Then, we need to hide this fact when we return" Eren immediately told him "Right, Armin?"

"Y-yeah. Levi-san, hear this" Armin gathered all his courage and told Levi what Ara and Keint said.

"I know that they were the one responsible in that accident" Levi told them "But since my uncle, and the military police were involved we remained silence to it. We just needed more evidence to present to Darius. Which will happen soon"

"We wanted to protect Xyril-kun but we failed it" Sasha commented and she was in verge of crying

"Your job was just to look after Xyril. But you don't need to do that now. I will look after Xyril, I have a simple mission to the six of you, and you need to group into two"

~Next Day~

Levi brought Xyril with him, and Erwin tried to tell him not to bring his son inside the site. But Levi assured him that he would look after his own son, and Xyril promised that he would behave.

As they were busy measuring the building and concretes, Hanson arrived and greeted everyone except Levi.

"You should also greet your superior, bastard!" Levi told him but Hanson just passed by him and went to his post, not far from where Erwin and Levi were

"Calm down Levi. Just remember what need to be done today"

"Erwin, Levi, oh my gosh, I knew you will be here Xyril-kun!" Hange shouted and the other workers tried to stop her from entering the site because of her weird tension

"Shitty glass, what's your problem?!"

"Levi, can I have Xyril-kun today? Can I have him today? Neh! I finally found that cake shop!" Hange's voice echoed throughout the construction site

"That cake shop?" Erwin asked curiously

"Yeah, the cake shop I used to go with (F/N)!" She shouted that made Xyril wanted to go "See?! See?! Xyril-kun wanted to go too! Neh, can I have him today?!"

Levi clicked his tongue and told Xyril to behave, even warned Hange that he would kill her if something happened to his son.

"Then I'll drive you to downtown. I have business there" Erwin told them and handed the report to Levi "I'll leave things here to you, Levi"

Levi's usual response followed.

~

"I can't believe it, Levi-san asked us to look after (F/N)-san" Eren whispered as they were standing outside the clinic where (F/N) was working

"But it brings back memories when Levi-san also asked us to follow her, and we ended up being played at by no other than (F/N)-san" Mikasa reminisce but Eren and Armin turned pale remembering it

"Ah, the verification case" They said in low voice

"Haha, that was a laughing matter but it was very embarrassing" Armin added "Everyone in the building found it funny. She is really genius in handling computers"

"It can't be helped. She is the genius leader of the computer science department that is responsible in the company's security" Eren reminded them

~flashback~

"Listen, recently (F/N) is acting weird." Levi stood in front of his team and confused to what order he would say. "I want you to follow her and report her activities"

"Uhm, Levi-san, that is our secret mission?" Eren asked him but received a death glare from Levi

"Eren, stupid, don't forget that in order for us to be in this team, we need to follow Levi-san's order. Also, we're not just Engineers, but special spies" Jean reminded him "Then, Levi-san, do you have any idea why is she acting like that?"

"Jean, Heichou will not ask us if he has an idea" Mikasa corrected Jean "Levi-san, we just need to follow her activities, and report it to you, right?" Levi nodded and the others just followed his order while doing their works.

In their company, (F/N) was the head computer scientist, who was responsible in installing mechanisms and securities inside the building they were constructing. She was also responsible in the company's high technology security.

Days had passed and Levi team couldn't find the reason of (F/N)'s odd actions. In contrary, they felt that (F/N) already knew that they were tracking her. It was proven that she knew already, when she asked them who ordered them to track her actions, though they didn't tell her

Levi arrived in the building's confirmation entrance with (F/N) behind him, emitting a mischievous smile. Behind them was Levi's Team

Levi headed to the fingerprint scanning and put his hand for confirmation and in order for the elevator to work. After all, in their company, they needed to scan their fingerprints for verification, and for them to enter the elevator

"Confirmed, Levi Ackerman" the system announced

"Confirmed, (F/N) Ackerman" Levi noticed the odd expression from his wife who just finished scanning her fingerprints on the women's side, and everyone was curious to why the system announced it inside the building. Usually it would just show up on the panel.

"Are you okay?" Levi asked as they waited for the elevator to go down from the top floor, not asking about the system announcement

"Confirmed, Jean Kirstein"

"Huh?!" Eren shouted when he scanned his fingerprints. Everyone around him laughed, and even (F/N) "What the fuck is this?!"

"Why is my name on your fingerprints?!" Jean shouted and scanned his fingerprints

"Confirmed, Connie Springer"

"HUH?! What the fuck is wrong with this system?!" They shouted as the Levi team scanned their hand but their names were jumbled, and added to that, it was again announced inside the whole building

"(F/N)-san?!" They looked at her with troubled faces

(F/N) laughed beside Levi as she cuddled to Levi's arm. It was then all the monitor inside the building changed and a word appeared followed by a percentage increasing

"Affirming, 58%" Announced by the system, showing the percentage on the screens

"Oh, so it is working" (F/N) excitedly said as Levi and his team looked at her, dumbfounded and lost to what she meant "Thank you for the good work" she winked at them

"What did you do?" Levi asked confusedly

"Well, because I need confirmation for a good name. But in able to do that, I need to have the main fingerprints, and for the activation, six fingerprints. Of course four males and two females. Good thing there are two who are not here." (F/N) answered and cuddled more to Levi "But of course, for the activation, I played a little bit to the people I used."

"(F/N)-san, don't tell me, you used the building's computer system to play prank on us?!"

"It's bad to do that, (F/N)-san!"

Eren and Jean whinned

"Eh, is that bad? I am the one responsible for the company's security. Also, I've been asking you why you are tracking my activities, but you didn't answer" The six of them looked at Levi whose eyes were close "Of course, I was a little bit mean to the person who ordered you that, right?"

"Affirming, 97%" The system announced and Levi noticed the excitement from his wife "Affirming complete"

"Ah, let see, let see" (F/N) looked at the big monitor on the first floor as she waited for the system announcement

"Affirmed, Xyril/Xyriel Ackerman"

"Xyril/Xyriel Ackerman?" Everyone in the building asked confusedly

"Formulating from Levi and (F/N) Ackerman data and fingerprints, Xyril is the best name for a male and Xyriel for female. 7 months, 2 weeks, 2 days, 9 hours, 22 minutes from now, the new Ackerman will be born. Affirmed, Xyril/Xyriel Ackerman.." The system announced repeatedly that made everyone in the building stopped from what they were doing

"Eh?!" Levi's team was the first one who reacted and Eren's voiced was the loudest "EHHHHH?!"

Levi looked at (F/N) dumbfounded to what he just heard

"Levi-kun, (F/N)-chan!!!!!" Hange's voiced echoed inside the building as she ran towards them "I heard the announcement!!! Congratulations!"

However before Hange arrived to where Levi and (F/N) were, Levi team stopped her and dragged her away, leaving the two.

"(F/N), just now?"

"As what you heard. I was planning to tell you privately since you hate publicity. But since you ordered your team to track my activities, I was a little bit mean-" however, Levi interrupted her as he slammed his lips to hers, giving her a long and passionate kiss

As he moved back, Levi kissed her forehead and hugged her tightly "I love you, (F/N)! Thank you!"

~

"In the end, our confirmation stayed as it was for the whole week. (F/N)-san said that she only changed the name, just the name" Armin laughed "and the prank she did to us became a celebration to her and Levi-san. By the way, Jean, Connie and Sasha, who are they going to track again?"

"Hanson Brake" Eren answered "Levi-san wants him to stay at the construction site."

"Commander Erwin" Mikasa mumbled and they all looked towards the direction where Mikasa pointed

"You are right. Why is he here?" Armin confusedly asked

~

"Tch!" Levi clicked his tongue as he stood in front of the site. The workers knew that Levi was irritated but they didn't know why

"Levi" Someone called him and he was surprised seeing the leader of the Garrison stood behind him "Your ambiance is overflowing. The place is not cleaned enough?"

"What are you doing here Dot Pixie? Erwin is not here" He answered and folded his arm. Dot Pixie stared at him, and Levi felt he needed to talk to him privately "Follow me. Mike, I'll just talk to him in Erwin's office"

Dot Pixie is the leader of Garrison police who are responsible in the country's defense. He is well-known, but rarely put things in action even though he knew something was going on. He knew something about the Military Police, but he because the Military police has a higher position, he just calmly observe the situation, siding to Survey corps.

Mike nodded and told the workers to add more lumbers and timbers. When Levi left, Hanson approached Mike and told him that he was feeling sick and needed to go to hospital. Mike gave him permission, but as he walked away, Mike was looking at him from the corner of his eyes.

Hanson planned to go to where (F/N) was since he unknowingly felt nervous when he left his house. However as he arrived outside the site, Sasha jumped down in front of him.

"Ah!" Sasha blinked fast and smiled towards Hanson but jolted when he heard Jean's voice

"Are you trying to run away again, Sasha?" Jean asked while scratching the back of his head

"Heichou will get mad at you if he finds out about it" Connie added and laughed then looked at Hanson "Ah, the man from yesterday."

"Please keep this a secret from Levi-san" Sasha grabbed Hanson's hands and pleaded "Please!"

"Eh?! Why should I?"

"I'll die!" Sasha said seriously "Levi-san will surely kill me. That man will do it surely. I failed him yesterday when Xyril-kun got lost! Levi-san is scary! So Scary!"

"Sasha, stop that. Please, just keep it a secret" Jean looked at Hanson and smiled "Ah, and also please don't tell anyone about what Sasha said"

"About Ackerman-san? That's because it is not true? Well, if you want me to, I can kill Ackerman-san for you. I killed a person before"

"It's true. It's just we don't want any other people know how scary Levi-san is. It's hell after all. Also, kill Levi-san? Good luck for that. If you killed a person, Levi-san killed multiple of those. Kill him before he kills you" Jean said in serious voice and face "Well, you don't need to do that. Heichou is scary, but he has a good side."

"By the way, where are you heading, eeto, what is your name again?" Connie asked out of nowhere

"Ah, I need to see my w-"

"Oh shit! Levi-san?!" Sasha shouted and ran away, grabbing Hanson to the opposite direction of the clinic where (F/N) was working

"Sasha is really good in acting when Levi-Heichou is in the scenario. Let's go follow them and make sure that he will not get in the way of their plan" Jean told Connie and ran after them.

~

"Hannes-san, what are you doing here? You supposed to be in the site-" (F/N) was interrupted when she noticed someone behind him and it was Erwin "You are with someone"

"(F/N), this is Erwin Smith, the commander in charge of the site, and also your cousin" Hannes said and (F/N)'s eyes widened. She felt her chest tighten

Hannes let (F/N) and Erwin talked privately, and he talked to his wife not to tell anyone about it.

"I assume that you don't remember me, (F/N). I am Erwin Smith. I am the commander in charge of the construction of the building in the center of Nikko City, the president of Wing of Freedom Company, and also your cousin." Erwin introduced and sipped the tea served by Hanes' wife "I heard that you met Levi yesterday"

"L-Le...vi?" (F/N) asked as if she remember something by just hearing his name "S-sorry, I don't know him"

"Ah, it's fine you have amnesia after all and I don't expect you to believe in what I will say. However, I will assure you that everything I will say is true and I have evidence that you are (F/N) that we know." Erwin smiled and handed a photo to her "I'll first start to that"

The photo was (F/N) when she graduated from high school, with Levi, Hange, Erwin, and Levi Team. Beside her was a tall beautiful girl with a long black hair.

"Me?"

"That's you when you graduated in high school. The girl beside you is your best friend Kaya, and beside you is Levi, your husband. And the rest, well, they are your close friends" Erwin explained but he noticed that (F/N) was still denying it "Don't think hard (F/N)."

"This person looks exactly like me. Probably that's all. I mean, Hanson told me that I am his wife"

Erwin got a note from his bag and handed it to her. "It's a site, your site actually. You posted daily video diary since high school up to when you and Levi got married. Please watch them. Also" Erwin handed another photo and this time it was the picture of (F/N), holding the new born Xyril, and beside her was Levi "(F/N), I don't know what Hanson said to you, but now that we found you, we need to secure you and protect you. Sooner or later, the military police will find you and will kill you" Erwin looked straight at (F/N)'s (e/c) eyes and seriously told her "That's why even though you still don't remember anything, at least follow what your heart is saying. Please keep this meeting from Hanson. If he finds out, he will surely kill you"

Erwin bowed down and left once he received a message from Mike that Hanson left the site. In (F/N)'s mind, Erwin's words were lies, but in her heart there was something inside her, urging and telling her that they were all true. Also she could tell from the photos in her hand that it was no doubt, it was her.

"(F/N), make sure to hide it from Hanson. That man will surely go hysterical" Hannes' wife told her as she patted (F/N)'s head. She also gave her time to open the site Erwin gave her, and she was surprised seeing herself on the video.

~

Levi asked Thomas to served Dot Pixie a coffee and a black tea for him. He also received a message from Jean informing him about Hanson.

"At least they are doing their job" He mumbled clicking his tongue

"Levi, I arrived back here at Nikko City yesterday, and I saw Erwin's cousin entering the forest" Dot Pixie started "I was surprised when I was driving down from Irohazaka road"

"So you saw her. She was being dragged by someone, right?"

"I don't know what's going on, but I thought she's dead?"

"We thought the same thing." Levi answered sipping his tea "that woman has an amnesia"

"Levi, I was with Nike yesterday. I don't know if he saw her, but still if the military police find out that (F/N) Ackerman is still alive, they will surely kill her"

"Dot Pixie, do you know something we don't know?"

Dot Pixie sighed loudly as he sipped his coffee "I just found out about this last week during my meeting in Akechidaira. The business partners she was talking about were spies in the underground mafia you are investigating for a long time. (F/N) finds out about it and made contract with them." He again sipped on his tea and seriously looked at Levi "(F/N) also finds that someone from military police is connected to underground mafia."

"Wait hold your ass! You are saying?!"

"I don't know who in military police, but he finds out about that. (F/N) Knew about it. So you can say that he might be the one behind (F/N)'s death"

"No, the one behind (F/N)'s accident is different person. But now it makes sense why the military police just closed her case out of nowhere. Not just because of the Ral family" Levi told him "But, how did you find out about this?"

"We finally opened the message she sent to us three years ago. It was short, but meaningful" Dot Pixie answered "Military Police = Underground Mafia"
