It's content is really bloated(so much grind...), clunky, and scattered(unnecessarily spread around in a disorganized manner) which somewhat creates the illusion of it being a bigger more fleshed out game than it really is but... honestly there's basically nothing there writing wise to make actually playing the game worthwhile. What you see in the prologue and what's in the sex scenes(not translated) is all the characterization you're really going to get for the characters, this translates to the entire game being nothing but an empty horrible grind.
The ONLY potential appeal I could see would be if you're skipping straight to the gallery after finishing the prologue, or are just really desperate for specifically "cuck" content, the MC has to go out of his way to make the girls give the other guys a chance for the other guys to have any chance, and it's not like he's unaware of what they'll do if he gives them that chance so I question how much this would really appeal to the broader NTR crowd, and on the other end the most fleshed out vanilla-ish heroine is the sister and you can't ever get with her since although she really wants it, the mc is against it. So it's just a case of trying to attract both crowds but not fleshing out the content of either enough to really be satisfying from either perspective. (Note: Aside from the sister just being a pretty basic imouto stereotype, the rest of the girls just generically like him cause plot and that's the entirety of their character)
Also the game is super loud and has no volume settings
