University art teacher Ji Zhimin cheated on a 20-year-old female student. Five years after the divorce, his first wife Gu Meijuan was diagnosed with terminal breast cancer. She cried and begged her ex-husband to take care of her son. Ji Xiaobao lived in the villa of his father and his mistress, pretending to be good every day, while secretly abusing his sister. Until a mirror shattered and the adoption certificate fell out - he was not his biological child. The moment the van hit, mistress Bai Muyu pushed Ji Xiaobao away, and hot oil poured on her hands. In the hospital, Ji Xiaobao finally called out "Mom". But no one knew that there was a knife hidden in Ji Xiaobao's drawer.
