Most people belive that vampires don't exist. However, they're wrong. Jung Jaehyun is a living proof. He's an eighteen years old no ordinary vampire who feeds on animal blood, unlike the others. He hated killing people, their blood out and drying them down. He wanted to have a normal life and be normal, just like humans. Jaehyun disowned himself from his family and moved to Seoul. He's living in an apartment, learning to live just like the rest of the city's population. He seems to be a cold and mysterious guy from the outside and it's all because of his secrets. He has to make sure no one knows the truth about him. Things are going really well until high school starts and he meets Kim Sojung. When a vampire develops feelings towards a human, things are beyond complicated.
