Zhao Xinhui (played by He Landou) and Lin Hancong (played by Cai Fanxi) have been close friends since childhood. Lin Hancong has always regarded Zhao Xinhui as his cherished sister. Due to the divorce of Lin Hancong's parents, the two experienced their first separation. In the years that followed, Lin Hancong relied on memories to support him through difficult days. When they met again, Zhao Xinhui did not recognize Lin Hancong. Due to Lin Hancong's family changes, he temporarily lived in Zhao Xinhui's home, and love gradually developed between the two. Lin Hancong's delicate companionship when Zhao Xinhui's grandmother passed away helped Zhao Xinhui come out of her grief.
