Regressor

First – the succubus thing is bullshit (the point of the regressor subset in Isekai or Harem fantasy is IMMORTALITY! * Fucking him over by costing him “life force” when you could straight up say CUM is you being foolish with implementation)

= None of the rendered females are actually attractive enough to put up with the bullshit you’ve implemented ham-handedly in this plot. (the step sister > actual sister??? is UNNECESSARY and RAPE CONTENT for no reason but to BE rape content * the mother is an asshole in general; and you forced an issue in the plot that was fixed > ONLY to then go and decide Nope! One of the employees with TITS fucks up… so MC completely screws over the whole stated LIFE GOAL he had just to save her arse. For what?)

You transition to a sandbox system with a hint system that COSTS you the use of your ability per day (with no means to make that happen MORE often – so you better hope you don’t add more women over time or you might want to call this game GRIND YOUR DAMNED ASS OFF INTO ETERNITY BOYS) AND no means to actually earn MONEY to build up your finances that DOES NOT ALSO COST THE ABILITY POINT PER DAY!!!

= The fucking POINT of owning his own company was GENERATING A PASSIVE FUCKING INCOME! Jesus mate. Your investment portfolio should be making you money each damned DAY. No matter what. With the small ones actually making you less. The big ones make you more but take more time to get the money to purchase (by using your power as the failsafe, or working shit jobs otherwise until you CAN generate said passive income by at least ONE point – AND THAT SHOULD BE WHAT THE PASSED MONTH IN SKIPPED GAME TIME WAS FUCKING FOR) This would create the means to incentivize players to WANT to keep playing, to see what scenes they can unlock. (You don’t need paetron codes, or cheat codes; you need to understand scale and economy. Budgeting, profit, and not going out of your way to fuck over the MC by any means you can manage)

Except all the girls are either already puppies who will never be hurtful to MC and are absolutely willing (chloe – who there was NO good reason to IGNORE for a whole damned month right after they’d just had sex; and you tagged PREGNANCY asshole… Think about that >.< ) or gold digging/opportunist bitches you WANT to use as the excuse to unleash a shit ton of unncessary misogyny. You’re writing this shit based off Solo Leveling and a few other Manga I can think of as far as the regression thing, but your main character comes off as an actual incel. Like the kind the feminists love to demonize. That’s not a good thing.

Harem is about ENDEARMENT and BUILDING relationships, with people who are WORTH THE FREAKING EFFORT to do so, my friend. If you can’t write that, you don’t have a harem. End of.
