Zhang Shujun (Li Chongwen) has a bright smile, and the relationship he and Zhu Na (Xu Encai) have known since childhood is always inseparable from Zhu Na. Beside Zhu Na, who was also traumatized by her mother, she has been guarding her like her brother for 20 years. However, when she didn't want to marry her sister Juna, Hyun-soo (Cui Zhenyun) appeared. From Xian Xiu, who always meets unexpectedly, I see the overlap between her and the girl who wiped her nose and blood after losing her mother as a child. If it is the last thing to protect Xian Xiu, there is a beautiful romance that does not let go of her hand.
