Youth is like a huge curtain. The young man's dark eyes and the unbridled men and women in his youth are like the colors that are constantly painted on this curtain, but he still moves forward desperately despite the pain. Gu Yihan's life may be a blessing or a misfortune. Everyone who appears in his life, such as first love, true love, and forgetfulness in the world, comes and goes. What is love? Humiliating, disdainful, hurtful. The joys and sorrows in life are nothing more than reluctance to let go, not getting it, and not being able to let it go. In the end, there is just one sentence: Where you are, I will be there. Have you let it go? Well, let it go.
