An ordinary autumn day. The school year has started quite recently... You walk through the corridors, wander back and forth, looking around, breathing in fresh air. Sometimes the gaze runs over the students around. Someone, like you, walks alone, someone has fun with friends. My thoughts go somewhere far away...

In any case, everything always comes to an end. You step out of the train of your thoughts, whether they are ordinary or not, by touching the door handle, which introduces you to your new class. After all, every new school year in Japan, the class changes...

The first thing that catches your eye is the gray crown of some guy holding a phone with an open game in his hands. You can't see what kind of game it is. Slowly stomping forward, you get closer to him. It would seem that he would not notice, but by chance your clothes touch this guy's back. He starts, turning to you and speaking slightly hurriedly, louder than usual, saying:

Aa? What...?

Thanks to this, you can see his face completely. He has pale skin, short gray hair,purple eyes. Have I seen him somewhere before...?
