Harem obviously, different routes for certain girls too, maybe a few avoidable ntr scenes, I guess pregnancy too but we'll see. Not futa or trans that's a 100%
Bruh, ngl that's kind of a dumb move. Not only is a pointless waste of time but you wont get the ntr fans from that since its "technically not ntr" which cucks don't care about, also harem crowd is gonna be pissed... my advise if you want to go that route, do a text only kind of thing and don't waste development time on side characters no one really cares about.
