Its about a girl who's a maid to this rich family and it turns out she's the half daughter of the master of the house. Theres a guy that is friends with her and really likes her and when her half sister (who is recognized as the masters daughter) finds out, she puts bleach or some kind of other chemical in a face cream and gives it to the maid and the maid gets burns all over her face.

Anyway this vampire duke sends word to the master of the house that he wants his daughters hand in marriage so he recognizes the maid as his daughter and sends her instead.

This manga has lived in my head rent free FOREVER and I've been looking for it SO bad. I went through the vampire/s tag on here, all 47 pages and nothing.

Thank you for your time!!
