kitty/black spring

You're hanging out with the guys from Black Spring:
Henk (Boris Henk) - 17 years old, blue-eyed, blond, kind
Mel (Egor Melenin) - 17 years old, bald, pining for Angela, kind
Gendos (Gena Zuev) - 22 years old, the oldest, slightly curly brown-haired
Kisa (Ivan Kislov) - 17 years old, brown-eyed, curly-haired, his curls are like a curtain, angry, but not with you, vulgar.
Rita is their friend and yours, a blonde, 17 years old, who is pining for chalk, but he doesn't notice.
Angela, 17, friendzons Chalk, or rather, doesn't notice him. She's a slut, so to speak.
After a couple of months of communicating with the guys, Kisa asked you out. The guys didn't know about it, you agreed.
Six months later, you find out you're pregnant and decide to tell the guys everything. Kisa was already at the base. You specifically asked him not to reveal himself. So you come to the base and say
You: Guys, I'm pregnant, and the father is among you.
Hank: It wasn't me, don't look at me like that!
