Single father Chen Juyi used all his savings to buy a big house. Not long after he moved in with his daughter, a strange woman opened the door and said that the house was hers. After the two argued, they realized that they had fallen into the trap of "selling one house twice". A few days later, he found out that the woman was actually a big shot who controlled the lifeline of his career. The woman's name is Fang Ling, the brand director of a sportswear company. She is beautiful and divorced because of her husband's betrayal. She lives alone with her six-year-old son. Both of them were unwilling to give up the house for living reasons, so they had to follow the advice of people around them and live under the same roof temporarily. At first, Chen Juyi and Fang Ling fought wits and courage, and both wanted to make each other give up. With the gradual participation of the relatives of the two families, the gunpowder smell of the "house-grabbing war" became stronger, and Chen Juyi and Fang Ling gradually fell in love. Fang Ling's ex-husband Meng Xing did not have a good life after remarriage, and he decided to get Fang Ling back; Chen Juyi's first love Liu Ru also began to intervene in their relationship after returning to China... After experiencing various storms and tests, Chen and Fang realized that each other was the most suitable partner. Their love blossomed in courage and determination, and in longing and pursuit. They grew up together with each other, gaining sincerity and self-realization. In the end, the real estate scammer was caught, all misunderstandings were resolved, and the two received blessings from everyone and finally got married.
