Qri and jungkook have been dating for almost 3 year now. They never hide anything from each other but qri keep having this feeling that jungkook is hiding something from her. One day qri went to jungkook house for their 3 year anniversary to found him making out with her best friend eunjung. Luckily they didn't saw her because qri use the key jungkook give to her when they first start dating.               

What will qri do? Will she seek for revenge or be a fool and pretend she didn't see anything, pretending nothing happen
