The life of 25-year-old swimming coach Zhang Shuai was originally uneventful. A job that I love and a girlfriend that I have loved for many years. Until that day, he met Liu Feifei, a 28-year-old student who was full of mature charm. Repeated encounters in the swimming pool, a dinner that crossed the line, and an irrevocable kiss made his life instantly out of control. His girlfriend's alienation, his master's warnings, and his clients' traps followed one after another. When the lie is exposed and trust is completely broken, he must pay a heavy price for his choice. This is a realistic story about youth, desire and growth, telling you that once some boundaries are crossed, you can never go back.
