Rein finds a mysterious someone or something? in the middle of a pile of garbage on her part time job. Who and what is he? He lost his memories, so he's living with her momentarily. He calls her mistress. He acts like a slave. But what happens when he remembers his past? What if his former owner-Fine comes looking for him? People are confessing. Who to who? Whose love will last?

They are all tied together by fate, which no one can escape. Ace disappeared when he was most needed by someone. Fine's wishes are all coming true one by one. Rein is developing a second personality which no one knows about. Bright is the shining "prince" in every girls heart...except for 2 girls? Shade puts on an "icy" aura, but can it be just an act? Whose this new guy-Kaito?
