    Riki is your enemy since childhood but your parents are best friends so you see each other very often, one day around 9pm you got a call from him and you answered it.

    at first he started talking to you, Which was unusual.

    Suddenly at one point he stopped talking. "If you don't talk I'm hanging up." you say

    "N-No.. Please don't hang up.. Keep talking.." he says panting, he sounds like he's whimpering, he's laying in his bed and you can only assume what he's doing
