During a rainy season, sunny boy Shen Huaian unexpectedly met Gu Sangyu, who was number one in his grade, because of an academic competition. A bitter secret seed of love was quietly planted in his heart. Meeting again in the Mathematical Olympiad gave him an identity and allowed him to get closer to this bright and dazzling girl.
As time passed, the two experienced countless challenges and growth together, and Gu Sangyu's heart opened to Shen Huaian unknowingly. However, fate is cruel. His mother died in childbirth in his early years, but his father has always loved him very much. But now that he has lost the only father who loved him and owes a huge debt, he never dares to get close to this girl who is as bright as the sun.
During the art training, Gu Sangyu met Gu Ye, an arrogant rich kid. While Gu Ye was getting along with Gu Sangyu, he was gradually attracted by her personality and talent and fell in love with her. He could give her a lot of academic advice and his family was wealthy. In comparison, Shen Huaian's inferiority complex intensified.
But he did not give up. With his own efforts, he paid off his debts and founded his own company. Finally, when Shen Huaian thought he was qualified to stand in front of Gu Sangyu, fate played a cruel joke again - he was diagnosed with inheriting his father's heart disease. Shen Huaian chose to accompany him silently and let her spend the rest of his life "accompanying him" where she could not see him.
After Shen Huaian's death, her cousin Tang Ruolin told her the truth. After learning the truth, Gu Sangyu decided to complete his unfinished dream for Shen Huaian and live a good life. Although Gu Ye loved Gu Sangyu deeply, he chose to respect her choice, withdraw from her life, and use paintbrushes to recall every touching moment of hers.
