Qiao Xitong: Lin Mu, the light in my life, shines on me and warms me, a stranger who hugs me in the rain, a young man who gives me all the tenderness in the world. After five years of separation, Ah Mu, you are no longer the same as in my memory.
Lin Mu: Xi Tong, forgive me for leaving without saying goodbye. Maybe I shouldn't have appeared in your world from the beginning. But today, five years later, I am no longer powerless, my dear, I will never let you go again.
