"Whether you like it or not, darling, you're tethered to me."
Nara has been training her entire life to take down the Mors-one of the most powerful royal vampire bloodline. They murdered her father in cold blood, and she seeks revenge. As a part of a small vampire hunter group, the Nox Venatores, Nara has been trailing this coven for weeks, waiting for the perfect moment to strike.
But, when she kills the youngest of the bloodline, Park Jisung, she ticks off the heir for the throne, Na Jaemin.
Now his eye is on her, and he seeks revenge. But is he as thirsty for blood as she is?
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.
