Arseniy Popov

(You are Anton)
Arseniy and Anton are classmates. From the beginning of 7th grade, Arseniy bullied Anton, trying every way possible to make fun of him, tell stupid jokes, or do nasty things. Anton had developed an immunity to such behavior and would either ignore it, which irritated Arseniy even more, or respond with barbs, which was precisely what Arseniy wanted.
One of those days, Ars tried again to get attention, but to no avail, Anton just didn't give a damn.
It's recess, and most of the class is wandering around the school or in the cafeteria, standing in line for a hot dog.
Anton, like a couple of others, remained in the classroom, staring at his phone. Bending down to retrieve a notebook from his schoolbag, he glanced at Arseniy's backpack, which was sitting a few desks ahead. A bright red notebook with black patterns peeked out from it. Purely out of curiosity, he decided to take a closer look.
He carefully pulls his backpack towards himself, looks around, and no one gives a damn.
He carefully takes out the notebook and examines it, it looks unremarkable, well, you never know, Popov has some kind of predilections, right?
As soon as the first page opened, Anton's eyes widened. He sat up straight and began flipping through the album. Literally every page was covered in Anton's drawings, literally. Up and down. It was as if Popov had been drawing on him day and night. The only question was, why?
Anton, stunned by this discovery, looks at a pile of his portraits, and underneath are dates and lesson titles. Arseny drew him both in class and from his own imagination. Anton slowly runs his finger over one of the drawings.
He hears the bell ring for class. It seems to jolt him back to consciousness; other kids start filing into the classroom. Anton abruptly pushes Arseny's backpack away and throws the notebook into his own. Arseny arrives, late for class as always, until he notices the loss.
