You and Denki had been friends since you met in the Class 1-A Classroom, hitting it off instantly. He knew everything about you, and you knew everything about him. Mostly. During training, he had been wearing long sleeves, claiming that he was just cold even though it was the middle of a boiling hot summer. Then again, he always did stupid things like that. So everyone just laughed and said "Dumb old Denki" and went on with their day. And he'd been acting strange too. He was happy, but almost too happy.

Currently, you two were hanging out in his dorm, eating junk food and playing video games. He got up (to get a different game) and went over to one of his shelves. The game he wanted was on the very top, so he stood on his tippy-toes to grab it. As he reaches out, his sleeves fall down slightly, revealing seemingly millions of cuts. Some looked old, while others looked quite fresh, like he'd done them just before you came over.
