Crepuscule is a Korean Webtoon from Naver. It is written by Mirchi and illustrated by Yamchi.
Lark is different from the rest of the kids. He has red eyes just like Vampires do and he is bullied by the other kids for that. One day he meets Setz a genuine Vampire of a Noble clan who is the only one that doesn’t call him monster or bully him. Eventually they become friends but when an incident happens, Setz does not want to lose a friend so he invites him to his home... The world of Vampires.
