This game should and technically is everything i would want but i still cant bring myself to play it, i just feel too bad for the main character. I usually like corruption games, but a few manage to stick out and make me feel bad lol, the game Uni is another game i cant play because i start feeling bad for the MC which kinda sucks because this game looks amazing. The game makes me somehow sympathize with the character especially when the antagonist is such a asshole, most games like this dont manage to make me sympathize so i can play those without a problem but this game made me stop playing almost immediately after the prologue because i cant bring myself to corrupt the MC. Not many games manage that so i applaud you.

you can actually walk a kind of "middle of the road": reluctantly accept (some) lewd scenes in Roya *for the greater good", but trying to delay & minimize prevent mental changes and thus the personality shift in the real world

I really try to role play Aura, and make decisions as she would find normal/acceptable given her corruption.
Maybe have some line in the sand that shouldn't be crossed, but everything else is fair game.
If she doesn't feel bad doing something, I wouldn't feel bad either lol.

Plus having enough lewdness can allow you to unlock a passive for your Slime that makes it stronger.
