Unfortunately, Chi Yu didn't have a good native family. She felt that her life was bleak until she met Gu Yuan, who was very good at studying, especially mathematics.
Chi Yu, who had been secretly in love with Gu Yuan for a long time, finally got to be with him as she wished, but her fate was unfair. In the second year of their love, Chi Yu was diagnosed with terminal cancer. At the same time, her online articles were criticized, causing her to suffer from severe depression. When he learned that Gu Yuan had won first place in a world-class mathematics competition, Chi Yu felt that the gap between himself and Gu Yuan was getting wider and wider, and they seemed to be drifting apart. She walked onto the rooftop, opened her arms, and the breeze blew across her cheeks
"I often advise others to live a good life, but I can't persuade myself."
Chi Yu stayed at the same age as Hua forever, so Gu Yuan blamed himself for not discovering her abnormality earlier and regretting not spending more time with her.
"I always thought math problems were easy, until I encountered the problem of love, but I couldn't find the answer."
"I'm sorry, Ayu. I didn't listen to you and I came to find you."
Concept: Love itself is an unsolvable proposition
