I'd like to put in a request to be able to...interact more deeply with the set-in-stone characters.
Nyan, for example. I discovered a soft spot for her after her quest, and went to all this trouble of running around during storms, beating up anyone stupid enough to challenge me, and looting them blind to get money to benefit her business.
She's a sub, right? I would really love it if there was an option where, after we get her Affection high enough, we could train her to be submissive (by way of kink potions and sexual training), and ultimately enslave her. Of course, we then put her right back where she was, running the clothes shop and all that, but we now have a whole new set of sex options, get regular money from the shop's profits...and gain a new slave, of course.
I'd really appreciate it if we could do that. And then I'd have to think about asking for some options to explore a relationship with the Valentine's Shop Owner. Which is such an adorably bad business decision, I can't help but want to dominate her and break her in a little.
