"I had a dream, Yi Yu. You will never know how real this dream is. It was so real that when I woke up, there were still tears in the corners of my eyes. We didn't speak for a long, long time, so long that I almost forgot what the voice that was lingering in my ears looked like every day. When your appearance became more and more blurry in my mind, , I dreamed of you, just like I saw you who had grown up. In the dream, I was also not brave. I was the one who first looked away after looking at you. Even though there were many things I wanted to say to you, I didn't say them out in the end. You looked at me with a frown on your face, yes, I am no longer your best friend. "
——Gu Jinyi
"I don't know if some of the things I have done will hurt some people, especially those I care about. I have never been as happy as I appear on the surface, and I have killed some emotions before they even sprouted. As Gu Jinyi said, I am the most cruel person, and I abandoned her when she loved me the most."
——Yi Yu
Yi Yu is the person Gu Jinyi wants to see in her dreams, but he is also the person she never dares to love without hesitation.
