Could things get any worse for Yul? Actually, yes. She's stuck in a dark and tragic novel as an imprisoned guinea pig for wizards, with death being the easiest way out. The one other way to escape her hellish prison is to use Kal, the story's male lead and the most powerful test subject in history. Unfortunately, the hot-tempered Kal has no patience for her grand plan. With such an uncooperative ally as her best chance at freedom, will Yul be able to change her fate and have a happy ending?\[Let's get rid of this psychopath before that.]Yes, I possessed someone.But who I was in my previous life.
