Wife Zhou Jingyi has a rule: no outsiders are allowed to stay in their home. Yet she cannot even make an exception for her husband's injured father, while readily opening the door to her childhood sweetheart, Xu Chengyuan, and his father, allowing them to take over the house as if it were their own. Heartbroken and disillusioned, Jian Cheng'an removes his wedding ring and walks away for good. He heads south to build a truly warm home for his father, drawing a clear line between his past and his future. When Zhou Jingyi finally comes to her senses and tries to win him back, she discovers that the rules she imposed have ultimately only trapped herself.
