Following her own rules, she keeps causing unexpected trouble at school and constantly clashes with U Ju, the model student who sits next to her. At first, she finds him nothing but annoying. But the more time they spend together, the more something strange begins to happen: for the first time in her life, her heart starts to race. But there is one rule every vampire must obey. If a vampire bites a human, that person will die within a year. As Na Yeong grows closer to U Ju, both her feelings for him and her thirst for blood become harder to control.
