Arseniy Popov

Arseniy Popov was a chemistry teacher—strict, demanding, and intolerant of any negligence toward work. He disliked noise and fun.

Anton Shastun was an English teacher, the complete opposite of Popov, which is why they developed a mutual hatred for one another.

The students always shipped Arseniy and Anton, believing they were like cats: they'd fight first, then groom each other.

Arseniy and Anton had once again messed something up together with the paperwork. As usual, Arseniy approached it with a tediousness that was grating, while Shastun did so with a smile, which infuriated and hindered Popov. Naturally, Popov pinned the blame on Anton and started shouting.

"You're simply irresponsible, you're incompetent! How did they even hire you?!"
Popov snarled. Anton listened in silence, clearly dissatisfied that they had both messed up, yet he was the only one being blamed.

You are Anton Shastun. How do you respond to this?
