His Dangerous Obsession

Lu Huaifeng is the Lu family's illegitimate son. A fight over interests inside the family business ends with men sent after him, and he is in a bad way when Song Xia comes across him on her way back from work and pulls him out of it. He wants her from that day. Song Xia's adoptive parents were killed by Lu Xuan, the eldest Lu son, who hit them with his car and drove on, and the family covered it. Lu Huaifeng knows and keeps it from her, holding her close to him instead. She learns it anyway. She pretends to have lost her memory, stays where she is, and works at getting hold of the evidence of what Lu Xuan has done. What she gets sets the Lu family fighting among themselves.
