Gu Sheng likes Zi Lu, but he doesn't know that Zi Lu also likes him. It wasn't until Ye Zilu took away her first kiss that she knew he liked her.
A year after Ye Zilu fell in love with Gu Sheng, she confessed her love, but was rejected by the delicate little girl. After confessing her love several times, Ye Zilu felt that actual action would be better.
Intention: I thought you liked someone else, but later I found out that I was the "other person" in your mouth
