"Brother Cheng, Su Su... Su Su is wrong... Brother Cheng, will you... Forgive Su Su?" These were the last words Su Qing left to Gu Ancheng. Why didn't Gu Ancheng want to forgive his Su Su? But Su Qing never gave him a chance to forgive. He watched helplessly as Su Qing slowly died in his arms. He knew that until the day Su Qing died, she hoped to hear "Su Qing, I love you" from his mouth. However, there was no such chance, never again. Only when she died did he realize that he loved her the most. He exchanged Su Qing's life for Nan Mo's peace. He, Gu Ancheng, failed to live up to the world, to Nanmo, to the people, to the late emperor, and in the end, he failed to Su Qing. Is it so difficult to hold your son's hand and grow old together with him?
