Zhou Yize and Su Lan were childhood sweethearts who knew each other since childhood. They were in the same class from elementary school to high school. Over time, Su Lan fell in love with Zhou Yize. But Zhou Yize didn't know that before graduating from elementary school, a girl asked Su Lan to give a letter to Zhou Yize. Su Lan hesitated whether to give it to Zhou Yize, but she still gave it to Zhou Yize. Zhou Yize read the contents of the letter and agreed to the girl's confession and they were together. Ever since Zhou Yize got together with that girl, Su Lan had been avoiding Zhou Yize, so the relationship between the two became weaker and weaker.
Purpose: Even if we have regrets when we are young, we can eventually overcome the barriers and fall in love again sincerely.
