Introduction: Gu Beixiao hugged Nan Sheng and gently stroked his back: "When I first saw you, I felt that you were the fairy in the painting and did not belong to this world. Your talent and gentleness made me want you to stay by my side. Even if your wings are broken, I still want you to stay with me!"... Nan Sheng caressed Gu Beixiao's thin face and murmured: "You are the only reason why I stay in this mortal world. Without you, there would be no Nan Sheng."
