There are 2 potential buyers afaik. One is Leonid, the other is that Sauna Madam who makes her repay the debt through prostitution. So you have that debt route already in the game right now, but Sveta isn't allowed to leave the sauna until repayment.
From a gameplay standpoint:
IMO if it doesn't heavily impact Sveta's life and the player's choices it would be a waste.
I used to get my goth char always pregnant with real father, thinking it fits the character I had in mind the best. This release I had her pregnant with the stepfather instead . Why? Because there's real consequences with stepfather and that is part of the fun even if it cuts content.
Would the player be content with Sveta the part-time slavegirl?
If the player wants the content from highschool, he can just do highschool and trigger this afterwards. If he's a new player and doesn't know about it, just list the escape points in the wiki. (as of now there is an escape point in the master's cellar, through that window)
Apart from that there's the narrative standpoint reasons of why I even started talking about this obscure event chain in the first place:
Who would allow his sex slave to school? One would only if the whole thing was some kind of LARP/fetish play.
and
Why does a sex slave needs school in the first place?
Furthermore, the sauna madam is the one with ruble signs in her eyes when she purchases Sveta, I can't imagine Leonid being so. And why make her do stuff holding the debt over her head, when he has something far better, like total power over her.? He can do whatever he wants to her without asking.
He mentions that she doesn't make him happy anymore.
Nonetheless, I was thinking he becomes attached to her. If Sveta is eager and goes beyond what is asked of her (like doing the actions for those traits for example), he'd start to sentimentally care for her (the relationship mechanic).
She definitively needs to meow now and then and end every sentence in -nya
I was talking about some piercings that aren't in game. And the rest of the piercings already ingame look like the clothes shops looked before: different sizes, different backgrounds, different bodies, different breasts, different pussies. If you'd use a single girl as a template and just photoshop them onto her, it would all look cleaner, organized.
