When she was young, Bai Zhilin met Jiang Qianyang, a neighbor's elder brother, and she stayed with him all day long. She had a small scar on her hand, which her brother remembered clearly. Later, due to family changes, Bai Zhilin moved away, and there was no news about her brother again.
In the summer of his freshman year in high school, Bai Zhimin suffered from "depression" due to his parents' divorce. After transferring to another school, he unexpectedly met him again on the way to school and became classmates. However, they did not know at the time that they were childhood playmates. Bai Zhimin, who had a withdrawn personality, was moved by Jiang Qianyang's enthusiasm.
Finally one day, the truth of the matter was discovered by them. They were each other's sweethearts and understanding. They turned from good best friends to lovers. Bai Zhilin's depression was cured, and he also realized his wish to be the big brother's sweetheart.
