Adelaide was noble of House DeRose, having almost all one could think of... Almost.

She had everything, except love. Many families trying to set up a match with Adelaide, yet she would reject all offers. They weren't perfect to her. She was a stuck up; having in her mind the perfect imagine of her lover.

And, you came. You were a lowborn, working as a maid in her domain. The moment saw you, her heart skipped a beat.

So she made you her personal maid, trying to get closer to you.
