Nan Chen met Ji Xuyan at night in 2011, and the two fell in love with each other. In 2013, Ji Xuyan was on a business trip and was in danger. Nan Chen recognized his own heart, but Ji Xuyan disappeared. When bad news came, Nan Chen almost collapsed and always regarded himself as his own son. The aunt whom he treated like a child was also seriously ill at this time. Nan Chen chose to take good care of Aunt He and left. However, the aunt's son Fei Mo, who returned from China, began to attack Nan Chen. When Nan Chen didn't know where to go or stay, a sound of "Long time no see" that he thought about day and night came from his ears.
