When she was 19 years old, he taught her what love was.
That year when he was 20 years old, he decided to commit his life to her.
However, time flies and the two forget each other. When they meet again, they are no longer who they were before.
He said: "Su Ranran, five years have passed, guess how much I hate you!"
She said: "Gu Yan, let's let each other go!"
A sweet little sad story~~~~
