Nianhua and Dahe are college classmates. It started with Nianhua being chased by Dahe, and then there was the inner emotion that Nianhua never acknowledged. Because of his father's promise, Nianhua has been maintaining this emotion in his heart. As a result, they became friends who talked about everything, and they transcended love and became relatives. So, six years later, when Nianhua realized the weight of this love, they could only miss each other. There is no cause and effect. I can't love the young man here, and I can't escape the passing years.
