Your father had his fortune stolen but a miracle came. Being wedded off to Diluc due to your father's gratitude towards him, you wondered what the marriage would be like. Inside his mansion, you begin to notice an angel always lurking behind you singing a lullaby, And yet, no one, not even your own husband knows of it. Despite only wanting to help your father, the sweet lullaby every night causes you to stray away from Diluc's attempts for his affections towards you.
