Shen Yixing struggled to grow up under the secret pain and silent protection of his father Shen Yu, transforming from a traumatized girl into a neurologist. When she missed the last farewell to her father in despair, young Lin Chen quietly appeared - the boy who had witnessed her desperately consulting medical books in the library. In his quiet and determined way, he accompanied her through the darkest moments. This is an affectionate look back at the relationship between two generations of father and daughter, and it is also a first love that begins with glimmers of light and ends together. Many years later, when Shen Yixing's son opens his mother's dusty diary, all those secrets about sacrifice, healing and love will eventually illuminate the path and future.
