All my life, I've only lived for just one purpose, and that is to kill Byun Baekhyun, the heartless Mafia Boss. Things suddenly took a drastic turn when I discovered that I am Baekhyun's betrothed bride.

Lee Donghae is a werewolf. He is son of an alpha and lives a very comfortable life. But his perfect world is thrown off balance when he is forced to marry a vengeful vampire prince, Lee Hyukjae.

They called themselves the "Valkyrie" coming through a portal hidden in the walls looking like fatal warriors and dragging me to their world saying I was their "Healer"  

The first time we met, she was kneeling at my mom’s feet, asking for forgiveness. The next time we met, we started a worship of the most dangerous temptation. The last time we met, I held up a gun and prayed that we may all be absolved of our sins.

 Doyoung doesn't think he could ever fall in love, until a certain Lee Taeyong appears stealing his heart only to leave him in the dust. Doyoung is left heartbroken until a couple months later he finds the other dating a cold businessman, Jung Jaehyun, causing him to think of a revenge plan. This plan may just be for revenge, but what if Doyoung gets more than what he bargained for?
