Na Yeong, the vampire transfer student from Romania. Zero social skills, zero common sense, but also zero malice. Although Na Yeong has clear standards and logic, she cannot adapt to the human world and constantly goes astray and causes trouble at school, but upon meeting U Ju, she feels the emotion of a racing heart for the first time. A young vampire who falls in love with a human, and a fellow vampire who stirs her instincts; a sweet yet deadly romance of youths wavering between love and instinct.
