His Nanny, His First Love

A young man and a village girl fell in love but were forced to part ways. He became successful; she suffered, forced to marry a cruel man. Years later, they reunite when she becomes his housekeeper, and feelings rekindle. Obstacles arise: his adopted son, ex-husband, and elders object. The male lead loses memory and power; the female lead guards him. Their biological son resolves the crisis. They overcome all barriers and finally live together.
