Thanks for clarifying, though I have a few lingerings questions
I assume that sexual comments increase the "corruption" stat of Aiko, but is that solely related towards placing her on the NTR route, or does it have other effects, like making her dress more sexy, or change her dialogue during sex? The latter would be a cool enhancement to the vanilla route I'd think, especially if their were modifications, or entirely new scenes because of it. My other suggestion doesn't fit the genre, but the thought crossed my head anyway of a reward for doing so well at the management aspect that the landlord is converted into a "simp" of Aiko's, and starts sending part, and eventually all of the rent to her as donations, maybe eventually just giving her the deed to the property if it goes far enough. Though I don't think any of that is likely, one because the landlord's character doesn't seem the type to watch a streamer, and the other because it would basically become a form of netori, which you obviously aren't going for. Still, I think something like that as a "reward" for doing well at the game aspect is kinda cool.
