I mean yeah, what happend was tragic. The Duke is really emotionally stupid. Tho that seems to be a trend, ugh reading too many books with emotionally stupid men. Like not a little dense, just outright stupid. How the fuck is raping your "boyfriend" gonna help?? You don't think to woo him... no flowers, no gifts, no dates, you just rape him?
And while I'm still mad about all of that the butler pops up. hahahahahahahah
That's one way to lessen the tension.
Like...what would happen if the authories were called? Would the loan shark even get in trouble?
I can only speak from a friend's experience-- when he got beat up by loansharks and rang the police they told him it was a civil matter and that they couldn't do anything. They pointed out that my friend borrowed from a sarakin, so it was all legal and that he should be responsible since he knew what he signed up for. It was a goddamn mess, but me and other foreign co-workers helped him out of it. This happened way back in 2012 though, so not sure if Japan's police stance has changed. More to answer your question though: if they're not yamikin, the police probably wouldn't do anything.
Like, perfect! Good looking out for you sister dude. I hope he becomes the king now. Let Bridey live in peace with Amon, and they can visit from the forest from time to time.
