@Siquall Tell that to I Should've Read the Ending, where the villainess also has a setting like this and the fl fails miserably at getting rid of her.
In fact, it's even more embarrassing, cause the villainess is a low level noble here, in ISRE she's a freaking commoner. The fl could've literally just ordered her servants to not let the villainess in her house, but no, she had to be a passive doormat that lets everyone walk over her while complaining in her head.
