Kang Taehyun is a quiet, mysterious, cold, and uncommunicative guy. He is always reluctant to talk to anyone, always alone when not with his only friend Soobin. He's in his last year at school and doesn't seem to stand out to any of the students, nobody notices him—except for his good looks. He hides a big secret — he's a skilled vampire who turned 134 years ago, but he looks 18 years old — that's why he always looks for other schools after finishing them so that hunters won't get him.
