How to Protect the Heroine's Older Brother

Kidnapping, murder, and risqué relationships! Within the scandalous pages of The Flower of Hell, the downfall of Roxana Agriche's criminal family is already foretold. So when Cassis Pedelian, the heroine’s older brother, is kidnapped by Roxanna’s father, she can either wait for the heroine’s revenge… or take matters into her own hands, since Cassis is the key to her survival. But with deceitful characters on all sides, can Roxanna and Cassis trust each other enough to bring down the brutal Agriches? I do not own this novel. It was written in Korean originally by the amazing Ji-Yeon Baek and I'm just doing my best to translate it.
