There were two important men in Cheng Sijin's life: one was Qian Cheng and the other was Wei Lai. When 3-year-old Wei Lai saw Cheng Sijin for the first time, he vowed to protect her and love her for the rest of his life. 15-Year-old Cheng Sijin met 15-year-old Qian Cheng. She liked him and he liked her. The three of them were inseparable for a long time, but Qian Cheng always felt that there was a thick gap between himself and Wei Lai. Others could not see it, but both of them knew it. On the day he turned 18, Wei Lai said to him, "Actually, I have congenital heart disease, and the doctor said I won't live to be 18, but I'm 21 now, and I asked the Lord of Hell for three more years. Because I'm not worried about Si Jin, but it seems that I have you now. So, Qian Cheng, in the days when I leave, you must protect my Si Jin, the Cheng Sijin who I personally raised." Qian Cheng felt for the first time that the usually omnipotent Wei Lai was lonely and sad.
