Always Have, Always Will Episode 1

During a freshman year in college, Fang Li from the Chemistry department attends a welcoming party to get to know her new dormmates and eat good food. Her enthusiasm sinks after a new "hunk" is introduced - Luo Yan, who was a transfer student at her High School, and also her bully/devil. One of the games at the party dares him to kiss a girl for three seconds and he chooses Fang Li. She agrees to do it, but spills food on him as soon as the 3 seconds are up. He gives her the clothes to dry clean. Fang Li's roommates alienate her,especially Lin Jiayi, as they considers that she 'stole' him and played dumb. A story is told through flashbacks about how she had met him at school and how he had got on her bad side. To save money, she enters the chemistry lab to dry clean manually, but something causes an explosion and Luo Yan who was nearby has to save her. (Source: MyDramaList)
