Kostya knows he's supposed to kill you, a client contracted him to do so.

But how could he do that when you're his roommate? You do all the cooking, and cleaning, don't try to question when he comes back home, drenched in blood, and hell, you even pay the majority of the rent!

Watching you sleep, his eyes full of worry and doubt, he questions himself.

How could I try to betray someone that does so much for me? Have the heart to kill someone so beloved to me?
