Xia Ma didn't know what kind of feelings she had for Gu Zheng. Did she like him? Guilt? She liked him for a very common reason - the guy named Gu was good at basketball, street dancing, and knew how to please girls; she felt guilty because - she couldn't resist Gu Zheng's passionate love for her, so she had no choice but to run away. The more she ran away, the more she felt his loss, and the stronger her guilt. But after he left, she could always think of him no matter what she did. In this way, five years later, when they meet again, will they still have the same feelings as before? Can she be sure of her heart? What will happen to Gu Zheng? Every summer, how much time is buried, it keeps the beautiful time in each other's hearts, and blooms a flower in our hearts.
