Li Nannan, a cardiologist, met Wang Moxuan, a talented legal scholar, through an online game. They fell in love offline in Shichahai. They played games together and traveled together all year round, and their love overflowed. But under the heavy pressure of the law firm, he repeatedly missed appointments and had ambiguous relationships with female colleagues, which drained Li Nannan's sincerity time and time again. Sun Tao, an orthopedic surgeon in the hospital, has always been silently guarding her, accompanying her during first aid and free clinics in mountainous areas, and providing warmth when she was most broken. By the time Wang Moxuan suddenly came to his senses and put down his body to try to save himself, Li Nannan had already completely withdrawn. Don't wait until I turn around before you say you love me. Your sincerity, which has been consumed by the cold shoulder, can no longer be held back.
