The game is focused (but not exclusively) around femdom. So yes; the MC gets, and will get pretty much dominated by some of the characters.
As for the grind matter: as you can see on the "Future content" section above, I'm planning on adding a sand-box mode where you can certainly accumulate some things like: affection/affinity points or currencies to buy stuff. It's subject to change, but you can check the 0.02b devlog for more detailed info <3
