I'm surprised that this turned out to be AVANTGARDE's best-selling game yet in spite of it being a game with romance and consensual-ish h-scenes (well, for certain values of "consensual" anyways) and them being a circle focused on NTR and Rape content.
My best guess is that, ironically enough, there's been a genuine lack of eroge focused around just being a guy who gets to bang hot girls in the japanese market. From what i've seen most releases in the last 5 years put you either in the shoes of a girl who goes around and gets raped or a guy who gets cucked, so for all intends and purposes "vanilla" content has been truly lacking out there. Them again, i AM a pregnancy fan who focuses solely on game with preggo and impregnation content, so this theory might be biased on my part.
Anyways - i hope the circle experiments more with male protagonist harem-based games, this is an incredible release and i can even forgive the very mediocre MTL due to the game's quality itself. (Seriously tho, someone needs to fix the missing translation in 2 of the womb tatoo h-scenes ASAP.)
