Su Sui is a person with severe emotional disorder and cannot love others. Lu Nian had been trying to find ways to overcome his illness, but it didn't work after all. In order not to delay Lu Nian, Su Sui wrote a letter and left.
Five years later, Su Sui became a famous author today. The books he wrote were deeply loved by everyone. At a signing meeting, his sister asked his brother Lu Nian to help sign the book, and the two met again.
Maybe it was the world's refusal to give in that made Su Sui jump into the river and pass away.
Intention: People who have difficulties should work hard to overcome them, and there will still be people in the world who love you.
