As good old Nafig says, if you're looking for a classic harem where the MC is an alpha male who effortlessly sleeps with every woman he meets, then this game might not be for you—at least not in the first season.
Don't twist my words. I said the player collects a harem of his choice. I'm not a pig, I don't eat everything. If the presence of character "A" in the harem is tied to character "B" and I don't like "B", I will refuse both. If we talk about the easy accessibility of women, then the most easily accessible women are in the NTSE genre. Take a calculator and calculate how many men/partners fuck one woman in a harem and how many in NTR/NTSE/sharing. My calculator is old, the screen is small, the number does not fit on the screen.
If you want to understand what REAL choice means to me, watch Exciting Games. Compare how choice works in your story and EG. Your story loses on all counts.
If FMC cheats on MC and he forgives her, there will only be one route in the game, the betrayal and cuckold slug route. Betrayal is always betrayal, it is NOT a harem, NOT sharing, NOT netorase, it is betrayal. There are no former traitors.
We focused on more complex dynamics, with a protagonist facing realistic situations and layered relationships.
This is pointless, because all your situations do not change anything and do not pose a threat to the relationship between the MC and the FMC. You have already stated “MC will endure and forgive”, there is no intrigue, in fact, you have told the ending.
P.S.
You have spoken several times about creating relationships close to real ones, I hope you will be consistent and not forget a few important nuances.
Cheating always kills trust. No man will fuck a woman who has betrayed him, he will be disgusted to touch her. He will not sleep in the same bed with her, will not go to clubs or restaurants with her. If the cheating happens during a photo shoot (as an example), he will not continue to do it, at least with her participation. He will not communicate or work with the person with whom she cheated on him.
Time will pass and some of the old relationships will return, but it won’t be tomorrow or the day after tomorrow.
I hope you take this into account in your story and give the player a choice.
