I Quit, but the Beautiful CEO Lost Her Cool

I've Run Out of Books to Read, Everyone

I'm looking for a book I read before, but I forgot the title. Before transmigrating into a book, the heroine was the leader of a bandit gang. Afterward, she gets together with the male lead, whose family includes younger siblings. He appears late in the story, while the heroine takes charge of disciplining his younger siblings at home. Oh, and the male lead's older brother and sister-in-law had a marriage arranged for business reasons.
