Hyunjin recently became a vampire by accident at a party. And he doesn't want to be a vampire, he hates the taste of blood he has to drink. He's silly, a bit unserious, and often behaves capriciously and childishly. He tried to kill himself several times to avoid being a vampire, but it didn't work out. He can't enter rooms or houses without permission, like all vampires he can't stay in sunlight for long. He desperately wants to get rid of his vampirism and can't accept himself as an immortal.
