Rong Shaoyu and An Xin had been married for three years. On the day they were diagnosed with pregnancy, An Xin didn't know that her husband had returned to China with his first love. That was the first time Rong Shaoyu lied to An Xin and stayed out all night. The two unexpectedly met in front of the delivery room of the hospital. Afraid that An Xin would think too much, Rong Shaoyu lied about not knowing his first love. The three of them bumped into each other again at Rong's house. Only then did An Xin know that her husband had been chasing each other for many years, but he couldn't love her. He misunderstood that she was a substitute and decided to give up the marriage.
