Momochi's Manga

This story was a surprise because I really dislike stories where the female lead is the empty head type and suddenly fall for a jerk male lead. However, when learning about her situation, the ML actually saved her from the hell she was living with the royal family, who only brought her just to sell her for power and treated her like trash. To the point she said being a slave was actually better than when she lived with them. So her seeing the ML as a none evil person is understandable.
Also the male lead is quite decent. He cares for the weak and innocent as well as his followers and despises those nobles hungry for power.
