The four good sisters in the play are Sun Yihe, a journalist who works in a TV station, Ren Ran, an executive who works in a famous enterprise, Wang Xinyi, a single mother who works in a gym, and Ding Ding, a girl who works as an agent. These four people all have their own problems when they are about to turn 30. In the face of these problems, the four sisters did not flinch, but even more faced difficulties.
Sun Yihe dares to endure hardships and work hard in his own work, but he is a little slow emotionally and always doesn't understand his true intentions. Although he is still an executive of a company, he is always modest in front of the person he likes. The saddest thing is that Wang Xinyi, who finally has to face her new feelings, accidentally learns that she is seriously ill.
The best should be tintin. She comes from a good family and is the apple of her father's eye. She also has her own unique ideas about feelings.
