In junior high school, Xuan Lin became friends with Qian Ning, and with his help, Liu Ruyan, the top student in the class, became his girlfriend. However, Liu Ruyan fell in love with the squad leader Lin Feiyu. Later, because Lin Feiyu's ex-boyfriend reported on her, she had to leave the town. After a fight, Qian Ning was expelled from school. Xuan Lin suddenly felt lonely and helpless, and his grades plummeted in the following studies. Later, he couldn't bear the torment of the disease and went to the county hospital for treatment. Later, he transferred to the county through connections and completed his studies. Xuan Lin met Lin Xiangchen who was late in high school because he was late at the same time, and became friends with him. Their friendship was short-lived. Xuan Lin then met his new friend Yuan Fei, but he was ridiculed as a "fool" by the other party, causing Xuan Lin to break up with him. In the second year of high school, Xuan Lin had a falling out with his classmate Wu Bin. This incident made him very depressed. At this moment, he discovered that a girl in the class had a crush on him. This gave Xuan Lin self-confidence and helped him muster up the courage to fight again, and finally passed the second grade in the college entrance examination.
Arrived at university. Without any restraints, Xuan Lin went to Internet cafes with his classmates to spend nights together, fought against the vice principal, and climbed over walls to break into rooms without any scruples. After that, Xuanlin was immersed in online games and couldn't extricate himself, and his studies were once neglected. After graduation, Xuanlin returned home extremely disappointed and unable to recover. By chance, he found that his first love Liu Ruyan and his former best friend Qian Ning were together. They also achieved great success in their careers. Such a blow made Xuanlin want to commit suicide by jumping into the river. However, in the cold river water, he suddenly woke up and finally decided to work hard and live hard.
