Qin Zhi is terminally ill, with death close at hand. Then another devastating piece of news follows: his older brother has died in a double suicide with someone else. Under the double blow, Qin Zhi is about to take his own life when a package unexpectedly arrives.
In it, his brother has left a final wish: Qin Zhi should help look after the child left behind by that person, Yu Weizhou. The child's name is Yu Zhao.
Though reluctant, Qin Zhi goes to find the child to fulfill his brother's last wish.
After the two meet, Qin Zhi doesn't tell Yu Zhao who he is. As they spend time together, Yu Zhao accidentally saves Qin Zhi several times when he attempts suicide.
After that, Qin Zhi gradually gives up on the idea of taking his own life. As he and Yu Zhao spend their days together, they fall for each other. During this time, Yu Zhao's mother, Tang Wanqing, dies, and Qin Zhi helps make the funeral arrangements. This deeply affects Yu Zhao. To comfort him, Qin Zhi promises that he will never leave him, not until death.
Yu Zhao fails his college entrance exams that year. Later, Qin Zhi helps him enroll in school again to repeat the year, and their study sessions help Yu Zhao improve his grades. But their “sweet” life doesn't last. Everything comes to a halt when Shu Xin, Qin Zhi's classmate from his doctoral program, appears.
At a dinner gathering, Shu Xin unintentionally exposes their relationship. When Yu Zhao learns the truth, he flies into a rage and fights Qin Zhi before leaving in fury. His second college entrance exam is only half a month away.
Frantic, Shu Xin and several others finally find Yu Zhao, who has a high fever. After they bring him home, Qin Zhi tells Yu Zhao everything, and eventually earns his forgiveness.
Just as the two believe they can spend the rest of their lives together, disaster strikes once more...
