Yoohyeon discovers diaries written by a stranger called Bora and finds out about a certain love connection that took place in the past. She starts to unfold the secret that has been buried for more than a decade and attempts to find the only love of Siyeon's life, but she gets too caught up with her own newfound confusing feelings that are blossoming every day towards one particular farmer girl, called Minji.

Vampires versus hunters. That's the classic thing. Coexistence between these two would be deemed impossible. But what if they had a common goal? What if not all vampires were the same and wanted to bring down an evil vampire clan too? Would Yoohyeon, who was a hunter for her whole life, team up with a vampire like Minji to defeat a common enemy? What if not all vampires were the vile creatures that the hunters thought they were? Sometimes we have to drop our prejudices and maybe, just maybe, the impossible becomes possible... coexistence.
