From the moment she was born, Kim Jangmi knew she was never normal. She was different from others, just like her whole family was. Every single one of them inexplicably attracts people and all other creatures, specially the ones that seek blood as means of survival.

Venoms, they were called. Their body fluids were deadly to humans and their bloods were capable of killing vampires.

Their existence, a threat to life. 

So her kind kept to themselves, refusing to be known as killers, keeping the secret only in their bloodline. They co-existed with people only up to a certain degree, and they were all forbidden any close relationships.

Until she met Lee Taemin.

Taemin was no Venom. But he was no ordinary man, either. Despite Minho's charm on Jangmi as her fiance, Taemin and Jangmi were both drawn to each other like metal to a magnet.

Afraid of what it might bring, Jangmi decided to uncover the mystery that was Lee Taemin. There was only one way to find out — which could also mean death to the man she finds herself falling in love with.

One kiss, and she will know who Taemin truly was.
