I can't imagine being 1 month behind on rent let alone 3. Where is she gonna cobble together that kind of cash in 3 days or 1 week? Also I wish I could "pay with my body", but no one wants a 40 year old dude.
In the H-Universe, "punishment" such as administered here is justifiable recourse for delay or failure to settle one's obligations. Opinions may vary as to whether this would be accepted in so-called "real life". And it can get quite complicated if the one being ... er, "punished" suddenly goes all "Hey Mikey I Think She (or He) Likes It!"
Nonetheless, artist's full fledged debut on FAKKU is "APPROVED!"
