The room covered with his finger tapping continuously on the wooden table. He was glaring at his team standing in front of his desk. Every movements he was doing, they would swallow their saliva, and their sweats would dropped from nervousness. With their hands on their back, they were hoping that Levi wouldn't get madder than what he was at that moment.

The tapping of his finger stopped as Levi crossed his legs and grabbed the report his team handed in.

The silence and tension covering them were broken once Hange opened the door widely followed by her loud excited voice "Levi-kun! Isn't he lovely?!"

She asked showing a 4 year old kid wearing a titan costume, while holding a human doll on his hand.

Levi looked up and still his stern expression remained, but his ambiance became darker and darker

"Shitty glass, don't play on someone's child. Find your own brat!" Levi retorted followed by his usual clicking of tongue "take that off from my son"

"Eh, but isn't he cute, right Xyril-kun?" Hange faced the kid that looked like Levi in front of her and the kid giggled in excitement "See?! He agrees with me!"

"Tch! Jeager, didn't I tell you to don't tell this shitty glass that I brought my son with me today?!"

Eren jolted and slowly looked at Sasha and Connie who were standing on his left side. He also turned to Jean, Mikasa and Armin who were at his right, but all of them looked away.

"S-sir! We cannot hide that from Hange-san, since Xyril-kun suddenly popped out behind Jean when we were talking to Hange-san!" Eren explained but received a death glare from Jean

"Well, well, it's fine. You six, go play with Xyril-kun. I need to talk to Levi in private" Hange told them, handing Xyril to Eren. The six of them heaved in relief that they wouldn't hear Levi's endless preach thanks to Hange, and so they thought...

"I still need to talk to the six of you. Meet me here at 3, and I need some explanation about this report" Levi warned them before they left

Hange chuckled but once the door closed, she put her hands on her white pocket cape and faced Levi "I'm surprised that you call Xyril your son"

"That brat is my son" He answered flipping the next page of the report

"As far as I remember, you never had a chance to play nor talk to him." Silence was Levi's response, ignoring Hange's words. However, he stopped once she continued "It's been three years. Do you think if she is still alive, she would like how you treat your son? (F/N) will surely get mad at you. But then, if she is still alive, are you going to treat your son like how you are treating him today?"

"Shitty glass, what did you come here for?!" Levi glared at her and a big wide smile escaped from her face

"Erwin told me that you and your team will be moved to Nikko City at the end of the month. You will be under his order to finish the building construction. You will be staying there for a month or more-"

"And who will look after the brat?"

"Hoho, so you still show concern towards your son?!"

"Shut up and answer my fucking question!"

"Well, Erwin order to bring him there, but not in the construction site. You can ask one or two of your team to look after him. Levi-kun, you cannot say no to him, right?" Hange teasingly answered Levi and then put down a small USB on his table "One more thing, Erwin asked me to investigate something. It was very disturbing, some actually. And then, because there's a password on some of them, Erwin asked me to give it to you since you might, no, you sure know them"

"What are you talking about?!"

"Well, well, try opening that USB, and you'll find a single, ah, no, hmmm, well you will see a folder there. Retrieving her files is very difficult, so good luck" Hange winked at him and left before telling him that she would also join them in Nikko City.

Levi finished all the reports from the building construction in Kyoto, but still need to talk to his team since they failed to finish one before the end of last week. He was about to stand but remembered the USB Hange gave.

Out of curiosity, he got the USB and inserted it to his computer. When he opened it, at first there was one, but when he opened that folder, there were two folders and a note. He opened the first folder and there were multiple videos on it. He clicked the video and his eyes widened when the face of his wife showed up, waving at the camera

"Today is my first day in High School. I will be attending a new school environment with my best friend Kaya. But I am kind of worried since we both hold quite a record during middle school. I just hope everything goes well. Also I heard that my cousin Erwin-nii is in the same school, but in different grade level and building. I hope we don't see each other. Oh well. I will report again later!"

The video ended with (F/N) again waving at the camera. Levi immediately clicked the date created to the latest one and was surprised that it was the date of their marriage. He opened it and was surprised seeing himself sitting at the edge of their bed

"Levi, say hi to the camera,"

"Are you taking your daily video diary again?" Levi asked while taking off his neck tie

"I am. Since this will be the last video that I will post on public. I will make everything in private now." (F/N) shifted the focus of her camera to her as she was still wearing her make-up and wedding gown. "I can't believe I am now (F/N) Ackerman. I am so happy! I can do more things with him. Those things! I can use what I bought online too!"

On the video, Levi could be seen shaking his head that made (F/N) giggled in excitement

"Don't tell me you posted our videos having sex? You took videos of every single sex that we did. Ah, except when we were doing it in the bathroom"

"Don't worry, I make sure I put them on private. I will not let anyone see my body except Levi! Of course, I will not let anyone see your body! Those eyes, those voice, they are exclusively mine!"

"Pervert"

"Only to you, Levi. And from now on, I will also make everything in private. Of course, bathroom scenes are special. So, this will be the end of this daily diary public version. Thank you for being with me since first year of high school!"

The video ended with (F/N) walking towards Levi, sitting on his lap, and giving him a kiss on the lips.

Levi stared at his computer for couple of minutes as he tried to comprehend everything. It has been three years since (F/N) got into accident and the police said they didn't retrieve anything except the car that they got at the bottom of the mountain cliff

According to the report, (F/N) was on her way home from her meeting with a business partner in Akechidaira, when her brake didn't work, resulting for her car to fall over in one of the turns in Irohazaka road.

However, Erwin and Levi found it weird since she was descending from the mountain. (F/N) was smart enough to drive the car up to the bottom of the mountain and there she could crash her car. For them there was more to her case.

But the military police closed the case and said that it was an unfortunate case.

Levi returned from his senses when his office phone suddenly rang.

"Levi" Erwin spoke at the other line "Hange told me that you received the USB"

"Yeah, I am checking it now"

"There are two folders, one without password and one with password. There's also a note in there with two links. The first link is a site where you can view her video diary in public. The second site, you need to have a password. But we cannot open the folder nor the site. We attempted multiple times."

"Where did you get this?"

"It's (F/N)'s" Erwin answered in low voice "The police gave me the USB from the things they retrieved from the car. I was surprised since they mentioned that they didn't find anything. Anyway, they gave me that USB and told me that it wasn't working. I met a computer scientist not working in our company six months ago and I curiously showed him that USB. He told me that the USB was made and customized that if it was soaked in water, it could only be opened again when it was inserted to the main computer where the content of the USB was created. I tried in her department, but it didn't work."

"That's why you borrowed her personal laptop"

"He was surprised since there were lots of coding to do when we opened it in her computer. But as you can see, we turned off the verification when opening the USB to the other computers. Still we cannot remove the password in that folder. So you might know the password and in there, we might see clues"

"I understand. I will be using her laptop then. I have an idea on what the password is, but I cannot open it using just the password. You know that (F/N) was a genius in using computer"

"Then I'll ask Mike to bring it to you"

Levi hang up and opened the other folder and indeed there was a password. He entered the password and he was right, the password was correct but it was asking for fingerprints verification.

"I am not sure if I can open it with my fingerprints using her laptop, but she is indeed genius" He mumbled and he ejected the USB
