Song Yiyi accidentally saved Yi Tianqi, her former fiancé who had lost his memory due to a car accident. With the joint efforts of the two, they solved many troubles encountered in the martial arts gym. Just when they thought that everything had calmed down, their feelings had warmed up and a wonderful life was about to come, Yi Tianqi regained his memory and forgot everything that had happened during the time he spent with Song Yiyi. After Yi Tianqi returned to the Yi family, he found that his grandfather Yi Xingxue was supposed to be recuperating from illness, but in fact, he was under house arrest by his uncle Yi Kunxiong, and the car accident he had experienced was not an accident at all. In order to rescue Yi Xingxue, Yi Tianqi asked Song Yiyi for help with a high reward.
