All it took was one letter for his world to turn upside down. Forced to attend a school with the same monsters that killed off his entire family- it was Ten's worst nightmare.

Before he knew it, Na Jaemin grew up learning the ways of the vampire hunters after having lost someone dear to him to one of those monsters; for that he vowed revenge. When he's on the doorstep to his future, he's shoved into a world he hadn't signed up for. With roommates and friends and the constant having to hide his fear deep down inside, he holds on tight to his goal in order not to lose it. But when he's thrown even more into the world of vampire hunters, it becomes increasingly difficult to keep both worlds separate. Especially when his heart as unwillingly opened itself up to someone he barely knows.
