Xu Yuexi is a teacher at a special education school. She is gentle and tough, and uses all her enthusiasm to protect those special children known as "children of the stars". However, her heart was filled with scars due to the breakup of her original family - her parents' indifference and quarrels made her lose confidence in love since she was a child, and the truth about her adopted identity made her fall into self-doubt. She closed herself in the world of work, using busyness to cover up her inner loneliness.
Xu Zhiyu is a returnee psychiatrist who is professional and calm, and is committed to using scientific methods to help autistic children. He kept a distance from relationships because of a failed relationship until he met Xu Yuexi. Her tenderness and tenacity moved his heart, and the scars in her heart also made him feel distressed.
The two met because of a charity event. From the initial conflict of ideas to the gradual understanding of each other, they got closer and closer in the process of jointly helping special children. However, Xu Yuexi's fear of intimate relationships, the sudden appearance of Xu Zhiyu's ex-girlfriend Gu Qingyan, and the recurring illness of her sister Xu Xingran all made this relationship full of tests.
