Well, i kinda overlooked the kinetic tag.
Just reminded me why i don't play those, forced LI's/relationships and sex scenes, like with Monica are what kills any enjoyment for me...but i played most of it, so my 2 cents.
The MC is a clown... what was that nonsense about only taking girls in his harem of which he took the virginity and they didn't have other partners ( jfc, this MC is so utterly pathetic )...at the same time the dude had no problems letting his wife fuck others...but then, i'm not a member of the ''lesbians are hawt club'', nor i'm into sharing, so what do i know...
Then there is the thing where one of the girls should 'pay' for her education...as if my opinion of this pathetic dude wasn't already low enough...and what is that crap with bringing her bf into his house...now i get that you probably try to make him a cuck, but there's exactly no way i would ever want that guy living in the same house as the MC and his girls...
On that note i can only agree with others here, the whole Monica plot is really bad, even worse for her character.
Genuinely needed to laugh once.
As the MC laughed that Monica's husband is a cuck, because he wanted her back when she cheated on him and how pathetic he is...
Like dude, you ''love'' her, she is still fucking another guy, is going back to him cause she loves him, tells how she ''loves'' her hubby after you just fucked her and you still go back to her, begging her to fuck you (and need his permission

)...you sure aren't the brightest one, are you.
While i'm not the largest harem fan and i prefer a good story. This whole Monica/MC situation is not any more realistic, or intelligent (be it from the MC's or Monica's perspective), then the most overused harem cliches .
And YES, if i play a harem game i expect the LI's to be mine alone...that's the whole reason i play a harem game...if i wanted to be eskimo brothers with another dude i'd play a sharing/swinging game.
So i asume what you wanted to do is a Netori/cuckold scenario, or at least a scenario which feels like it for the players.
If you want a good Netori scenario it's mostly preferred using a LI in a bad relationship, often also a bad partner.
That is because if you use a LI which is happy, in love, cares for her hubby and the husband is a good dude, you make her really unlikeable if she's happily cheating on him.
On the other hand, a LI in a bad relationship, with a shitty husband ? It's understandable why she'd be ready to cheat and the player may even like to humiliate the dick of a husband.
Also the whole point of Netori is to make her yours and yours alone. The hubby isn't allowed to be with her, maybe you even want to give him a front chair when you bang his wife and humiliate him.
What you did is making a sharing/swinging scenario, not really popular in a game aimed at harem players, even less if it's forced.
As for Monica, she is absolute unlikeable, i wouldn't want to touch her with a 10 foot pole. Be it her cheating on the guy she loves, speaking bad about him, or let others speak bad about him and her 'forcing' her husband to be a 'cuck' is vile (if she actually cares about him in the slightest)...like man, even ntr games have more likeable girls, at least the ones who break up with their partners, to be with the guy they want...
And i use the term ''love'' here very loosely (be it the MC with his...questionable outlook, or Monica)...because if this how Monica shows love i don't want to know how she is to people she doesn't like.
If she is not a LI, why spend so much fucking time on her ? Spend it on actual harem girls.
So, the MC doesn't really care about her (besides being hole to fuck) and most of her scenes aren't important for the story either, as a player i don't care either (or rather, i dislike her)...what is even the purpose of this whole situation with Monica ?
Because frankly, the game would be better without her, or them being just friends...
