Qi Shulan (Pan Hong) used to be a teacher. After retiring, she devoted all her thoughts to her granddaughter Tingting (Wang Zhixuan). However, what Qi Shulan did not expect was that her daughter and son-in-law's marriage had changed, and the two chose to divorce. At the same time, Tingting's ears were accidentally deafened. Faced with the sensory disability, the little girl was extremely depressed. Qi Shulan wanted to take care of Tingting with all her heart, but her former son-in-law eventually obtained Tingting's custody and entered the palace of marriage again. Uneasy about Tingting living in a new family, Qi Shulan stayed with Tingting under an assumed name as a nanny. Qi Shulan's approach was questioned and criticized by many people, but she didn't care about it. The smile on Tingting's face was her only hope.
