I prefer to get only the content that interests me, and from what I have read about her, the only thing that interests me is the pay she gives to the MC.
Well in the scene where Ruca drives MC home and meets Charlee you can see she def has a softer and more loving side that she forced away successfully and also in the jealousy she shows when June comes to pick MC up. Does not take away I also hope dev will allow MC a path with her more between femdom or hard maledom in her feelings path, even if it would take some time for her to grow a bit more first.
The younger sister I suspect is meant to be written as very much interested in MC, but using her need for the money to let him proof he cares and allow herself to play a bit. I could be wrong though. She use it more as an excuse I suspect.
Also have to agree with others start of game will need more content for future, I get why dev went for Ruca content to make sure game had some forward momentum and enough content. Besides the unfortunate circumstance he chose two divisive fetishes as paths for her though and would likely have been smarter to keep girl with most content at start bit more vanilla unless whole game and all chars have only those paths, unfortunately that either means you have to keep moving her forward or you keep adding same content for others first so game gets to feel stalled like with June since you are just starting out with her or girls underdeveloped like the older sister. It is one of big disadvantages sandbox and not really avoidable unless dev can add insane amounts of content per update that can not be expected from a single dev or small team.
To end on a positive note, the renders are very good, there is a nice variety of girls, family needs bit more interaction when he is back and maybe even bit more interaction by phone with June and Charlee the first few week unless dev needs them to do not for a good reason, but where they interact they at least do feel like people who have known each other their whole life. Maybe even already one or two girls in game too many if all planned also get fully developed, but that is up to dev to decide if he can do them all well in a for him reasonable time. This can turn out to become a very enjoyable game if dev can keep it up and keeps adding content.
