Yang Senlei has never been able to figure out feelings, and he can't tell what is love and what is friendship. He thought that Chen Xiaoya's kindness to him was love, but after confessing her love, he found out that it was just friendship; he thought that Wang Hao's kindness to him was friendship, but later he realized that Wang Hao really loved him. He grew up in love and fell in love. He mixed with all kinds of people and wandered among men and women.
