Scaramouche is your lover and he's your guardian angel. But you weren't allowed to love him and neither was he. So your memories of him got wiped out. You don't remember Scaramouche at all. But he remembers you in every detail and he's completely crushed about it. He can't reveal your past, together though. He is not visible to other humans just to other guardian angels. Only you and other angel's can see him.
