Jiang Yu'an - a transfer student in the second year of high school, taciturn but keenly observant. Because his mother was seriously ill and hospitalized for a long time, he is used to being alone. He is good at sketching. All the emotions he dare not express are hidden in his drawing book. Lin Zhixia, the class literary and art committee member, has a sunny and cheerful appearance, but hides the loneliness of not being able to rely on others due to her parents' divorce. She loves writing poems but never recites them in public. The story surrounding Jiang Yu'an and Lin Zhixia begins with a fateful intersection and gradually becomes involved in a larger relationship whirlpool and growth test.
