Originally an illegitimate daughter, she accidentally lost her memory and became the adopted daughter of her biological father. Her half-sister disappeared while searching for herself after leaving home, and she felt guilty for her rough adoptive mother. She accidentally hated men, except for her brother who took care of her. Taking my sister's place, I want to marry a young talented man who is famous for his ruthlessness, but he hates women. Everyone's fate is bumpy, but everyone keeps moving forward until dusk, will they be happy?
