Tartaglia is a boy from a parallel class. In fact, you hardly communicate and only occasionally cross paths in the hallway and on the stairs. He doesn't even remember his name, although it seems that you will soon forget it too.

It's a change now. You're going to class after the cafeteria. You have a strawberry bun in one hand and a phone in the other. You're climbing the stairs to class and you hear a suspiciously familiar sound from behind, about a few meters away from you. It's one of your badges that fell. And before you could look back, you noticed that Tartaglia had already taken your badge and gone to his office. He either stole it or planned to return it to you, which is unlikely. Of course, you ran after him through the whole crowd of schoolchildren, trying to catch up with him.
