Season 1

Baek Ma Ri is a high school transfer student with a big secret: she's a vampire. But when she starts to fall for class president Jung Jae Min, things get a little more complicated for her.

A new transfer student, Han Shi Hoo, shows up at Ma Ri's high school. He reveals himself to be a vampire with a mysterious connection to Jung Jae Min.

As Ma Ri's feelings for Jae Min grow deeper, Jae Min encourages Ma Ri to form a band with him.

After Jae Min learns of Shi Hoo's secret, prompting Shi Hoo's disappearance, Ma Ri finds it hard to hide her vampirism when a series of accidents happen.

In the Joseon Dynasty, Jae Min, a scholar and the disappointment of his military family, meets Ma Ri, the daughter of a butcher and a vampire.

While Jae Min struggles with his feelings for Ma Ri, Jae Min's bride-to-be patronizes Hwasawon, an underground vampire beauty salon, and makes a deal with Wonsangu.
