I'll add this to the beginning for those of you who came here to find this out: This game has few scenes about sharing and is mostly with two different characters, not the main chick - one with the other silver-haired who's her daughter and one absolutely random chick that you only fuck about twice then throw away. These scenes are however not optional and will appear naturally throughout your gameplay even if they are not the focus of the game; if you're really turned off by having scenes with more than one person on the woman, a person alongside the mc on the woman, or a person other than the mc on the woman and him knowing/watching, regardless of if the MC cares for them or not, then know these scenes are in this game.
HOWEVER, for the main character, there is only one optional and avoidable "shared" scene at the very beginning of the game. This means that about ~80% of the game is just straight netori (you stealing the girl), no sharing. Take of that as you will.
I decided to bite because of the artstyle as I'm sure many of you probably did. If you're here reading a review you're probably undecided on "does the art carry this game that well?"
The answer is no. No, it does not.
The plot is painfully average to completely stupid, the "gameplay" is repetitive clicking to grind money and stamina and then 'training' her by following a more-or-less predetermined CG progression. The CGs are good but I'd like to add that whoever had the idea of having a red flash when climaxing should rethink their choices because it makes for a jarring experience; I straight thought my character had been stabbed or something until I realized there is no way this story would ever attempt to even minimally interest me.
The only time the gameplay even SCRATCHES interesting functionality is visiting different places to progress the story of about ~two other characters which are not that interesting, and the game will warn you of it.
The English in this is not perfect, but it's passable - not good enough, sadly, to help the writing become less boring, but not bad enough to make you not feel like reading.
The "game" (if you can call it that) is also painfully short, about 3 to 5 hours max depending on if you skip the scenes you're not interested in (as I did for a few things).
The NTR part at the beginning of the review explains all there is about the CGs; the sharing is extremely stupid, the netori is done very badly, and if I'm honest the main female lead is essentially a doormat. I've seen RPGM games have NPCs with more personality.
For a netori game where you'd usually want your storytelling, progression, and of course the main woman's development/character/writing to carry the setting and game this is painfully below average and the only saving grace is the art style.
