In the same university dormitory, three best friends talked about everything and agreed to rely on each other for life. Graduation is like a watershed, pushing the three of them to completely different life trajectories.
Some people marry into well-off families, and everything goes smoothly and glamorously; some people struggle in ordinary marriages, struggling to make ends meet; some people waver between careers and relationships, unwilling to be mediocre but repeatedly hit the wall.
The gap in class, marriage, and family status has gradually changed the close friendship in the past. Envy turns into jealousy, concern turns into comparison, asking for help turns into use, and careless words turn into deep-seated resentment. The sisters who once talked all night long were tempted, hurt, and alienated from each other in the pull of reality. The pure friendship in the past finally deteriorated completely due to desire and gap, leaving only a place of lamentation.
