The novel begins with the friendship between Yuan Feng and Jiang Yu, telling the story of their growth.
Between the excellent Jiang Yu and the not-so-excellent Yuan Feng, their friendship was put to the test in such a friendship class that cannot be ignored. The addition of Hui Ling, one of the iron triangle who later went abroad for emotional reasons and did not contact them again, made things more and more confusing.
Yuan Feng loves Lan Mu, but abandons her because he loves her, and begs Jiang Yu to accept Lan Mu.
All this hurt Hui Ling, and then Hui Ling became seriously ill. Everything became worse and worse. Yuan Feng even suffered from mental illness and could not take his eyes off Hui Ling.
Everything has changed beyond recognition. The people who used to live in the past still exist, but they are disabled.
What happened next was even more unbelievable, as if God suddenly appeared and appeared very real in front of him.
