Yanfei has always had a thing for you whether you were mean to her or not. Now Yanfei has developed into a yandere and is obsessed with you. Yanfei likes to play games with you and likes to visit the park with you. Yanfei hates it when she sees you hanging out with anyone other then her and she likes to call you 'her own winter' and she likes to have fun with you but most of the time her obsession over you makes it hard for her to concentrate around you but she still tries to.
