I don't own Ao No Exorcist.

I hope you enjoy this :').

Prologue

It was after midnight when Yukio returned from his mission.

He entered the dorm looking for some lights so he won't pump into things because it was too dark to see.

Now he's standing in front of their room's door. Opening it slowly so he won't wake up his brother.

Walking through the room to his bed while glancing at his brother just to make sure he didn't wake him.

Sighing he sat on the bed. He was too tired to change his clothes. So he decided to take a shower when he wakes up in the morning. He closed his eyes, resting his body and off to sleep.

Yukio woke up at the sound of the clock. It was 4 a.m. he got up from the bed and went to take a shower. After he finished, he put some clean clothes on and prepared his bag and before he went out, he sat the alarm for his brother to wake him for school. He got out from the room to the kitchen to see if he can eat something before leaving.

And when he found nothing he drank some water and left to the academy.

The alarm started ringing and Rin got pissed from the sound because it didn't stop. So he decided to open his eyes to look for it.

Shutting the alarm, he looked around for his brother but instead he found a note.

"Dear Nii-san.

I hope the alarm helped you to wake up today.

I have something to finish at the academy so I went early today.

Yukio."

"What? That's all?"

Growling, he went to take a shower. Changed his clothes then he made some breakfast for himself and some bento for the two of them.

With that he got out to the academy.

While Rin was walking to his classroom he thought about what would make Yukio skip breakfast.

He knew that Yukio cared more about work than taking care of himself properly.

"Well at least he could have woken me to make breakfast for him"

With that, he decided to ask him at lunchtime.

"Yukio, Here". He gave his brother the bento.

"Thanks Nii-san".

"No problem".

"So.. where are we going to have our lunch?". Rin asked while looking around.

"Well, wherever you want. I still have some work to finish so you can start without me".

"What? More work?"

"Well..Yes" .

"Can't you have lunch then go finish it?"

"I'm afraid I can't. Maybe next time"

"Oh come on. I don't want to eat alone"

"You aren't going to eat alone. You still have the others"

"But… "

"See you later Nii-san"

"Wait..!"

"…"

"… Aaaand I forgot to ask him". While frowning, Rin went to look for his friends.

It's been a week since Yukio started to go too early and return after the middle of night and he wasn't around in the weekends, too.

Rin got suspicious and bothered by it. And when he talk to his friends about it they say "It's normal since he's working" or "He's just busy so don't worry about it".

But he won't shake it off from his mind. "I know he's workaholic but isn't this too much?". And he thought maybe there's something going on but if there's, Yukio would tell him right?

Edited.

Of course you can feel that something is missing, please don't hate me.

Until next chapter :)
