Kind of elaborating on what Ben here said, I really do think this game has very different vibes compared to others in this category.
It has a very big focus on the emotional side of things and while the cast does off course consist of ridiculously over the top characters you'd expect in a porn setting, they don't quite feel as unrealistic? Like, you are convinced by your mistress to go to therapy and it turns out to be a genuine therapist trying to help you work through the issues you have with your parents and not some hypnotist trying to brainwash you.
The entire Relationship between MC, their girlfriend and the couple they get into a cuck/ntr relationship with, feels a lot less like your usual over the top sissyfication plot and more like a genuinely wholesome kink relationship.
Even the subplot of the "Bully who steals your childhood crush" seems to be slowly going more into a "you two weren't meant for each other, but now you can openly share the joy of living out your respective fantasies with each other" direction in recent patches.
Now, I don't want to make it sound like "this is the one good sissyfication game" or anything. I think it'd be kinda silly to say that "more realistic and emotional relationships" are what people are looking for in their porn games. It's nature also causes it to be increadibly slow paced as far as the feminization aspect is concerned, so if you are in it for the porn, there is a decent chance you'll get bored by the time we get to "the good stuff". But I do think this is an interesting contrast to other games of the genre and if you like sissyfication games, you should definetly check it out. Especially if the Idea of submitting to a caring older man who can take care of you sounds appealing. (that being said, if you don't like Sissification games I doubt this is the game that'd change that for you)
