Ruru Hikaru's Manga

Cho Sunwon finds his life boring and tedious. Sex is the only thing he isn’t sick of, but it’s getting a little too easy to talk any guy into bed. He wants a new life, a new world, and a new challenge…and he totally gets all of those when he’s summoned into another world as the so-called god of Abroria! Awesome, right? Except, nobody seems to fall for his bedroom talk, and there’s a sexy king hell-bent on exposing Sunwon as a fraud. Seducing the gorgeous men around him without blowing his cover is going to be quite the divine challenge.

I love this so much! MC x Killer. Sweet sweet relationship. Is it wrong to hope to find my own killler and be kidnapped deep into mountain and spending lovey dovey time with my cute serial killer?

Mystery, fated lover and supernatural. Interesting. I wish there's more romance and yaoi but its quite interesting too when this story focusing on adventure and the romance is only side story.
