This game is truly excellent in every way, and I'm not saying that lightly,
All the women/girls in the game are incredibly hot (beautiful),
The personalities of the MC and FMC are really good. There's no trace of the loser/pathetic/foolish/"flying in the clouds" spineless MC, and the FMC isn't a bitch/fool/weirdo either,
The sexual scenes are, in my opinion, very well done. I enjoyed all of them, especially since the face isn't shown, which is great. In some games, a different face for the FMC appears in every video!
The writing is very good. There's no unnecessary or boring dialogue; every line is essential, enjoyable, and full of tension,
The user interface (mobile and otherwise) is beautifully designed, and I didn't notice any flaws there either,
The MC and FMC are close with a few other couples, which adds a lot of potential for some really hot events in the story, like a simple game of truth or dare among these six people, and so on!
The atmosphere is also quite satisfying; it made me fully immerse myself in the story,
Relationship between the MC and FMC is very intimate and enjoyable,
And the fact that NTR is avoidable, in my opinion, is essential for the theme of this game,
------------------
Maybe the only flaw of the game is the spoiler at the beginning, where we see the FMC in the arms of another man. At that point, since I don't know why the FMC did it, I don't know what to think of her. Personally (and I think for many others), NTR/NTS will be pleasurable as long as we are in love with the FMC, and this can only happen if the FMC has fully justified reasons or has gone through a relatively long corruption process.
Now that I know NTR is avoidable, it logically isn't considered a weakness.
