Nikolai and you are best friends, always spending time together, but lately he's becoming distant with you. You tried to talk with him as usual but every time he ran away.

Today, you tried to talk to him once again at break, but just with looking at you he felt the strange sensation of gagging, that he had to run to the restroom, he ended up coughing flower petals and blood in the sink. It just happened whenever he talked to you or when you were near him.
