@Crookshanks I am unsure how you consider trapping someone unwilling and actively trying to imprison them by social obligations even after your deal has run through and been completed as "being a good girl"
And in addition to that, she seems to love berating him? Can't tell if she thinks that somehow lets her assert dominance over him so he obeys her (thats not how it works), or if it just makes her feel good.
You know he kinda brought it upon himself
? She punished him by grounding him and started being his mom for 2 reasons.
1. He lacks common sense and gets into trouble constantly and she worries about him.
2. He splurged their shared funds (yeah, he got a lot of it, but the girls helped out quite a bit as well, they were planning to share them) on personal equipment. All 8 billion E which was equivalent to 8 billion yen which, yet once again, is equivalent to 56 000 dollars! Dude splurged 56k USD in one day on some whim shopping (useful, yes, but whimsical). Even casinos in Las Vegas don't just drain you that much in a single night! Moreover, both her and one of their main allies in the city got a blemish on their reputations because they had to beg the shopkeeper to lower the price just "a bit" (by about 14 000 USD...). Understandably she got pissed
