Jenny isnt new and that scene is already in the game if you chose the master slave relationship.
The only girl not presented as an "li" is Ashley, the withe haired girl and maid of Chloe.
The game doesnt feel like a harem though, based on what we can see in game it's everyone fucking with everyone,
What they do in the past isnt a problem, but Chloe said that she wont stop whoring herself, and same with Abi with party and fucking around, the maid Jenny is also fucked by a few guys already when she supposed to be close with mc, so more close to sharing/swinging but the not avoidable kind .
I wonder what's the point with the stat system though, lust and corruption feel redundant since both are tied to sex, and every girl starting at 0 lust and corruption doesnt seem normal either when all of them ( except maybe Jenny on one path ), should have a very high score in both based on how they act and talk. (hey at least should have each a different base in each stat based on their personality like it was kind of done with Jenny with love and sub.
