Lan Xiao, a freshman at a medical university, is a woman with a sad past and a stubborn character. Her father passed away when she was 10 years old, so she has a serious Electra complex. I really want to leave this city where I grew up and have many happy and painful memories. I went to college in the faraway city S. In order to support myself and pay tuition, I had to work in a high-paying bar. I had a lot of fun and met people I shouldn't have met. . . How nice would it be if we could just pass by? Without you, there is no past. . . Maybe that's not how it ends.
