It starts off well, it almost looked as if it was going to break the trope of the main antagonist blackmailing the female protagonist and in a well written manner (the antagonist wins her over with skill), buuuuuuuut a good few hours into the story, with a good slow build up to the first naughty deed, the writer uses said trope.
I'm fine with the blackmail trope, it can be real naughty and kinky, but the problem with the moment the antagonist uses blackmail, and after, the story starts to lose a lot of it's tempo. It seems like it can't decide where it wants to take the characters. One moment, the antagonist is all loving, and romantic and sweet (and genuine), the next he is a blackmailer.
It feels like the writer was trying to break some NTR tropes, and they start off brilliantly in this attempt, but it falls onto said tropes and after that, it seemingly can't decide whether it's a romance novel, or an NTR one. This can also be seen in it's music choices for certain scenes. It's like the first sex scene, the music is a bit TOO jovial for that moment - a faithful wife is cheating on a loving husband ffs!! That's not even mentioning how complacent she is in agreeing to it (no resistance whatsoever). As a result, it loses a lot of it's immersion, and doesn't seem to have a fixed direction.
Edit: I've rerated this game because at end of the day, I look forward to it's releases. I feel like it's finding a better tempo, and a better method of getting the female protag to willingly cheat. I think the dev has tried to escape the NTR trope for blackmailing, and still misses the initial mark. However, as the story has progressed, they've used a better dynamic to get her to do the naughty deed by focusing on something more realistic. She hasn't been converted into some braindead nympho through the use of blackmail, nor does it feel annoyingly unrealistic.
