Di.

Dee was sitting in history class, writing something in his notebook (something outside of class), and the historian starts calling on the board to recite some paragraph, which, of course, they hadn't studied.
Historian: To the board... To the board, board, board...
While the historian was choosing who would go to the board, the bell rang and everyone began to gather.
Historian: Hmm... Lucky you.
The historian muttered and left the office. Then, during recess, the fire alarm rang because something had caught fire in the cafeteria. Everyone quickly ran out the back entrance, and Dee barely found Heavy (his brother) and Leaf (you).
Di: Finally found you... Di got embarrassed during the video of Leaf (you), and Heavy started teasing him, something like "What's wrong with you, Di, are you in love?))".
Dee: Fuck, Heavy, shut up, will you?..
