The story tells the modern urban love story of a private photographer (Jiang Wei) and his mistress (Shen Wei). His parents' urging for marriage and all kinds of emotional entanglements made him, who didn't believe in love, become numb. Until he met Shen Wei, the client's bestie, during a photo shoot for a client, and fell in love with her, and secretly took a photo of her looking back. He got Shen Wei's number from her bestie and sent a message asking to be his model. In a situation where Shen Wei was entangled by a rich second generation and couldn't get away, he replied to the text message and asked Jiang Wei to help him out. After a fight with the rich second generation, a thrilling car chase began. Shen Wei also eliminated the barrier with Jiang Wei. When the relationship exceeded the initial prediction, the softness deep in the hearts of the two was actually deeply touched. Jiang Wei prepared a special shoot for Shen Wei, and the "underwater photography" quickly heated up their emotions. They officially confirmed their boyfriend-girlfriend relationship. However, there are always unexpected things in life, and the sudden appearance of the godfather broke Shen Wei's seemingly peaceful life. The godfather gave a month as the deadline. To be more precise, the meeting between Jiang Wei and Shen Wei was destined to be a love game. However, Jiang Wei, who was unable to extricate himself, also accepted this series of facts. In this last month, Jiang Wei did his best to be good to Shen Wei, and the relationship after this month would become a burden to each other. On the last lingering night, Jiang Wei quietly put the ring on the sleeping Shen Wei. Jiang Wei shed tears silently, but had to watch his love about to leave. On the day Shen Wei left, Jiang Wei tried his best to catch up, but Shen Wei had to harden his heart and drive away. Jiang Wei immediately left the city, and the two lost contact. However, things took a turn for the better, and two years later they met unexpectedly at the airport.
