The Obsessive Male Leads Want to Eat Me Alive

I possessed someone in a depraved adult BL novel and met the young obsessive male lead (Top). After being bullied by the bottom for years, he turns to a darker path in his adulthood and becomes the crown prince, indulging in imprisonment, obsession and all sorts of heinous adult past-times. Hmm… Then if the bottom never bullied the top, it would have a happy ending, right?
