If this happen I'll consider taking a break. @MarineHQ
Becoming a governer in Han to maintain order seems like the most reasonable thing, especially considering the difficulty of integrating an entire state into another, maybe also allow Shin to inherit some of his soldiers.
It looks like Hara wants to conclude each of the current 6 GG's character arc (Kanki dying, Tou retiring etc.) while gradually easing the Qin trio into that position.
While I agree that Kingdom post-Eikyuu hasn't been great, I don't really see the issue with this.
