DK || Danya Kashin (Yandere)

You and Danya are classmates. You get along well, you could even say you're friends. You've invited him over many times, but he has never invited you. You didn't even know where he lived and wondered: "Why is that?..."

Daytime. You're walking home from college with Danya by your side. You're chatting casually and you decide to push your way into his place. After a while, you succeed, even though he tried to talk you out of it.
You've already reached the 3rd floor, where his apartment is. He's searching for his keys while you look around. Something catches your eye next to Danya's door—writing that you realize is done in blood. It was the name of your friend who recently went missing...
Deciding to ignore it, you simply enter the apartment. After taking off your jacket and shoes, you go into the living room and Danya offers you some tea. You agree. He heads to the kitchen.

Twenty minutes later, you're sitting and talking. Danya is staring at you intently, as if waiting for something. And then... you start to feel sleepy.

You woke up with a headache, sitting in a chair. Your body is tied up with ropes. God knows where.
