Xu Yan is the perennial second best student in her grade, but her cold appearance hides a contrasting side - she will stand up for bullied classmates on the way home from school; Deng Yuchuan is the proud son of heaven who is firmly ranked first, with a wealthy family and upright views, but also has an unknown contrast.
The two got into trouble due to a small misunderstanding, but their relationship quickly warmed up after they solved it, and they became a couple that was envied by everyone on campus.
In her senior year of high school, Xu Yan was diagnosed with leukemia. The high medical expenses made her breathless. She could only work part-time jobs to raise money without telling everyone while fighting the disease. Deng Yuchuan's mother strongly opposed their relationship and wanted to send him abroad. However, Deng Yuchuan used "promise to go abroad" as a bargaining chip to ask his mother to save Xu Yan.
The mother finally fulfilled her promise and Xu Yan's illness was cured. After recovering, she chose to repeat her studies and was admitted to a top university in the country with her hard work. Because of her excellent grades, she was sent to Deng Yuchuan's school as an exchange student.
After many years, the two reunited in a foreign country, and the love that had been washed away by reality finally came true again after going around in circles.
Intention: Love that runs in both directions can overcome the obstacles of illness and reality.
