Isshinjou no Tsugou de (Akuratsu) Koushaku-sama no Keiyaku Maid ni Narimashita

Lulu, the daughter of a poor merchant, becomes a maid for the Marquis family in exchange for helping her pay off their debts. The head of the family, Gerald, is so impressive that the ladies all admire him, but in front of me, Lulu childhood friend, he's so arrogant and nasty! Lulu vows quit being a maid as soon as she pays him off! ... While she was working engrossed in the job, he attacks her, saying, *"Just be honest and let me spoil you,"* and demands that she sleep with him!? Is that even a maid's job?!
