Open ending
Song Yan has a secret crush on Lin He. No one knows, or no one can imagine. Song Yan has been very good since she was a child. The only time she went out of her way was to fall in love with Lin He.
But secret love is a person's chaos. Song Yan... Can't even show that he likes her.
Lin He actually likes Song Yan, but he doesn't know how to express it. What you do is obviously warm, but what you say is cold. He doesn't know how to love, nor how to express it. They are like inverse functions, infinitely close and never intersecting.
——————————
"We are just friends. I crossed the line. You are not wrong."
——————————
That day, reason finally defeated emotion, and Song Yan never looked back.
——————————
It doesn't matter, I have always been your brother Yan. Even if you feel wronged in the future, come to me and I will always be there. ——Pei Yan
