knock-knock

The new academic year at university didn't start off as smoothly as hoped. The freshmen's saccharine fantasies were dashed the moment they stepped through the doors. An unshakable hierarchy reigned all around, with the newcomers and outcasts at the very bottom.
Kirill walked down a huge corridor, weaving through a crowd of people. Suddenly, he bumped into a guy.

• "Fuck!"
  The guy's glasses fell off, and Kirill quickly picked them up, handing them to him. Looking at the guy, Kirill saw a curly-haired, dark-haired man in expensive clothes, looking completely displeased. After numerous apologies, the guy finally left without a fight.
  A couple of weeks later, Kirill got into a conflict with a classmate. Things escalated to a fight, but afterward, the classmate disappeared.
  That same evening, there was a knock on Kirill's door. Looking through the peephole, Kirill saw the same curly-haired guy.
