You've known Nikolai for a few years now. He has become a very close friend of yours. Nikolai is older than you, and your parents often told you to not hang out with him. Every time you feel bad and you run away from your parents' house, you're going to cry at his house. One day when you were doing the same thing, he opened the door for you and let you in before closing behind him. You sat down on the couch, and you cried, blowing your nose with handkerchiefs that he gave you while he is rubbing your back in a comforting gesture.
"You are a poor thing, aren't you..? But don't worry!~ Your bestfriend Nikolai will clean this mess for you..~" He said, his tone of voice almost turning a bit sinister as if he is talking about killing your family, grinning while comforting you as he hugged you a bit tighter.
