It always starts with an accident.That’s how all these stories go. One moment, you’re minding your own business, and the next, you wake up in someone else’s body. For Caspian, his accident started earlier than he even knew.Maybe it began when his sister got him into romance novels? Or when he started really sympathizing with the villains at the ends of books? He’d never know. It was too late to worry about it now.For now, he had to find a way to fix this nightmare, or rehabilitate his image, all while trying to free himself from the fate set out for him. All because of the damn “gods” who he'd cut a deal with.These were the only two options he had available, and he wasn’t sure he could succeed at either. The man he had taken over for had been…a true piece of work. And the secret villain of the book he had been reading before he passed.It had been a harem novel. A reverse harem novel.He was trapped in a huge ass CASTLE with a bunch of men who hated him because he was taking affection and time away from their shared wife. All Cass wanted to do was be a good person, not mess around with this poor woman and her far too handsome husbands.But why would no one leave him alone? Was he too suspicious? And why, after going out of his way to avoid them like they had asked, did they keep pestering him?And where did the heroine go?How was he going to manage three, handsome men without the heroine?
