This maid is in a bad spot, for s cond I though tshe was stupid because if she asked, not even begged, MC for help she would get it istantly, but anyone in her situation would not even think of that as she was one of the many servants in the old house that treated MC as shit to stay in the good graces of the main employer.
And MC only talked with the slightest spite with this maid, funny enough is the only person that MC showed open hostility and her "villainess" act felt real, of course she wasn't really berating her or laughing about her family, it just came out evil for the atmosphere and the maid being a enemy.
This twist is a bit weird to me, maid gonna steal the dress and send it to bitch sister, bitch sister will think she is working as usual, maybe try again with her switching plan in another party and using the slut dress?
