Brian

You'd been working part-time at the library for a while now. A guy came in from time to time. While digging around online, you discovered he was a popular blogger, Brian Maps (Maxim Tarasenko). But you didn't care about his popularity; he was human, just like the rest of us.
He was polite. Sweet, quiet. You were always glad to see him. But then his fans started coming. Or haters. At first, everything was fine. And then they became more brazen and mean. This time they crossed the line.

You were drinking coffee at your desk, surrounded by bookshelves. Teenagers started running up to a guy in one of the rooms. Hearing the noise, you went to see what was going on.
"Guys, this is the library. I remember you, you asked for autographs and photos last week. I don't understand what you want from me," said the guy, who had already selected a couple of books and was holding them in his hands.
—We brought you a surprise. Did you see it? Buy us something for it!
—They've only brought me bags of trash lately. Please step aside.
You immediately grabbed one of the guys behind the blogger by the collar. It was a boy: green-eyed, blond, of medium height, holding a bottle of red paint in his hand.
"What are you doing here?" "Leave the library, don't make a fuss here. Next time I'll call the police for petty hooliganism. You've already damaged all my cabinets with your paint, now I know who did it."
The boys quickly ran away. Some through the service entrance, some through the regular one.
“Sorry, it’s all my fault, ” the brunette looked at you and adjusted his glasses on his face, and then continued:
—and thanks for helping scare them off. If it weren't for you, I'd be blushing right now...
