Seduce His Uncle, Ruin My Family

Ivy Green is held by the Hunt family's rivals, the Sung clan, beaten and locked up, and she pretends to have lost her mind so they will leave her alive. Her grandfather is killed. She decides the way out is Leon Hunt, and she seduces him to get herself carried off the estate. After the night together he learns she is engaged to his own nephew, Marco, and breaks the engagement off. He also exposes what the Sungs have been doing and takes her back to her family's house. He knows by then that she used him and helps her anyway. She brings down her sister Laura by proving the writing Laura passed off as her own was ghostwritten. The Sungs answer with plots, with a bomb that turns out to be fake, and Leon keeps standing in front of her. Ivy forces confessions out of them and the authorities come for the family. She finds out who killed her mother. Somewhere in all of it she stops using him and starts loving him, and a year later he fakes an illness to make her say so.
