Young vampire Jungwon was given a chance to finish his unfinished business in the world when he died due to honorable death that he himself doesn't remember. He was sent back to live for another day as a reward. 

Taking this chance, Jungwon decides to do everything that he wasn't able to do when he still alive. 

Ultimately, finally taking out his anger on his of a teacher, exposes a cheating that always out to piss him off, or mayhaps confessing his love for his long-time enemy/crush. 

He doesn't have to think about the consequence anyway.
