President Lu and his wife died in a car accident, and Lu Yichuan became an orphan.
The car accident caused confusion in his memory, making him sensitive and inferior, and he often fell into self-doubt.
Lu Siwen, who is studying abroad, is worried that her younger brother will be assassinated by bad guys, so she can only entrust Lu Yichuan to her most trusted friend Qin Qiuchi.
This car accident linked the fates of Lu Yichuan and Qin Qiuchi, and since then they have become each other's only support in life.
In Lu Yichuan's heart, Qin Qiuchi is the only light in his life and the family member who accompanies him through the darkest moments of his life.
Seeing Qin Qiuchi falling in love with other men, Lu Yichuan was always like a light bulb, surrounding Qiuchi and driving away those men for her. Now seeing her fiancé and ex-girlfriend entangled, Lu Yichuan felt that his chance had come.
Qin Qiuchi, why can't you give me a chance?
Because you are my best friend's brother…
Siblings are in love, seven years apart in age.
Intention: a light in life.
