Hyunjin is a totally normal human that does totally normal human things. Like going to school, messing around with his friends, and more fun human stuff. He's very outgoing and extremely flirtatious, especially with the 'cutie' of his friend group. Totally normal human things for a totally normal human... except he has a secret. Two actually. Sam is Hyunjin's twin brother, who is kept a secret. He's a not so normal human that doesn't do many normal human things. He doesn't go to school, he only has one or two friends, and he only really socializes with people when he leaves his room. He's kinda shy around people but also has a cold attitude. The complete opposite of Hyunjin. Except they have one thing in common. They're vampires. And Jeongin is just a boy that goes to school and makes friends. Although, something sparks his curiosity when his friend starts to act weird around him. His very flirty friend at that. What happens when word gets out about the twins?
