Zhu Ying was born and raised as a boy by her father. She cut off her long hair at an early age and learned business strategies. Even when she entered the country's top private Ningshan Middle School, she had to hide her daughter under the pseudonym "Zhu Ying" and hide her body as a man.
She is a liberal arts genius who has read poetry and can decipher the core of thousands of poems. She pretends to be a gentle and reserved ordinary boy. She lives in the same dormitory with Liang Shen, a special student from a poor family who was born in a remote mountain and has the highest talent in mathematics and science in the school.
Li Wencai, a young man from a wealthy family, showed his kindness to "Zhu Ying" in every possible way. School bullying surrounded her at all levels, and the shackles of family marriage had long been placed on Zhu Ying. She thought she was recreating the story of Zhu Yingtai's studies in ancient books. She just wanted to survive three years of high school safely, but her heart was moved while spending time with the silent, clumsy, sincere Liang Shen day and night.
An accident in the locker room, whispers on the rooftop, and a burden three kilometers behind the mountain, secrets are revealed, and there is nowhere to hide the feelings of young people. Li Wencai's possessiveness, the overwhelming criticism from campus public opinion, the Zhu Group's business game, and the irreconcilable control and resistance between father and daughter followed one after another.
A breakup letter severed the bonds, one young man sank into self-destruction, and the other was trapped in the cage of a wealthy family. When the truth about class, bullying, and family conspiracies is revealed, two teenagers separated by fate choose to fight back side by side.
There is no tragedy like a butterfly dying for love in an ancient tomb. After separation, suffering, fragmentation and liquidation, Zhu Ying sheds her male disguise and calmly stands in the sunshine as a daughter. Liang Shen crosses the gap of birth to keep her original intention. Many years later, the shadows of butterflies fluttered by the artificial lake. They were no longer the butterflies and flowers bound by the world, and finally lived an independent and free life, running in both directions.
