There is a monster in my mind. A monster who loves taking control when my emotions run wild. That’s how I hurt my classmate and get into trouble—until a handsome stranger appears to take care of the mess I've created. Konrad Teivel is a mysterious man with serial killer vibes, but when my foster parents practically hand me over to him on a silver platter, I have no choice but to follow him wherever he goes. He takes me to a place I did not his home—a castle with white walls but secrets darker than his soul. There, I meet his family and friends, all of whom welcome me with a surprising warmth that he does not possess. They call themselves my biological parents' friends and treat me like their own, but that only raises more questions in my mind. Where have they been all this time? And why, among all of them, is Konrad the only one who treats me as if I were his worst enemy? As more people enter my life and the secrets about my family and origins unfold, I finally find out the reason. However, by then, it's already too late to change the past.
