He once thought that if he stayed with the young master all his life, being a peaceful housekeeper, watching him marry and have children, and maybe watching the young master grow up, his life would be complete. Even if it hurts, it doesn't matter. This is his duty, the fate he has had to accept since birth. However, a dream completely disrupted all his plans. He has a mission when he came to this world, and this mission must be completed, and it must be completed before he reaches his prime. Love, hate, and hatred in the world may be nothing but meaningless things in the eyes of immortals, and many years are just a blink in heaven. There is no afterlife, so we will never see each other again, separated by heaven and man, we will be apart for many years.
