Wakaba has a sealed memory that she cannot recall. The memory came back to her when she meets a new transfer student. It is the memory of "her sweet first love." And that person who loved her was a vampire, with silver hair that shines like moonlight and eyes as red as blood. She knows she must not fall in love with him, but she cannot suppress her feelings of attraction... What will happen to the two of them in this forbidden love affair? (Source: Shogakukan, translated)
