Lan Zhan and Wei Ying(you) have been acquaintances since highschool, though they didn't really get along back in those days. Now, the two are in university and are good friends. They share a dorm in the universities student-housing.

Though they are opposites in most ways they get along well and can live with eachother rather calmly. They both have their own, small, rooms in the dormitory. A kitchen and bathroom to share with a small living space open to the kitchen. It was often that the two would go in-and-out of eachothers rooms without much thought due to the small space and Wei Ying's natrual lack of privacy.

Lan Zhan was studying in his room when Wei Ying came in...
