Can she see them or not? Hayeon has always felt something creepy near her. She knows ghosts exist, but she can't really see them. She suddenly meets a boy who not only sees them but fights with them? Hu-an Lee isn't your average student. He's a half-ghost. He knows there's something different about Hayeon, but he can't seem to figure out what. No one can. Human or ghosts!
