I like that title.
Well, having a live-in maid take care of you and live with you for quite some time...It's no wonder something would happen between them. Still, I applaud him for actually making a move rather than do nothing.
That ending though. Hmm...Honestly, I don't think the condoms are needed, but that's fine too, I guess. Maybe one day she'll go from 'maid' to 'wife', eh? I mean, the way she does things like welcoming him back at the door, cooking for him etc would be a maid's job...But also that of a young wife, I'd say.
Almost makes me wonder if his parents planned for this to happen when they 'suddenly' had to leave for 2 months and hired a housekeeper.
