I didn't see many of those scenes yet. I got two endings, I guess they're both Haruka endings. I'm working on getting the other ones, I played it blind the first time and mostly chose the meaner options. I really like how there's so many option, and a lot of them actually branch off into a different scene entirely. You don't really see that very often anymore.
But yeah I really liked it, I liked tone of the game, I really like Minao, she's so obedient and eager to please. Really a bit of a unique character, she comes off as desperate, but it's more like being extremely willful rather than that. Kinda almost admirable, it's clear she doesn't particularly like being treated as a slave but she goes along with it anyway.
I also like that she isn't like sheltered or naïve or shy. Usually when you get a character this obedient like this, they fall into one of those handicaps. But, she's kinda just average and normal.
Protagonist is very good too, takes a very practical and kinda professional attitude to training her. I like the rules and stuff too, a lot of everything he does has meaning to make her feel more like a slave and make her enjoy it more and want to be a slave. He’s got a very dominant personality is the best way to describe it. Quintessentially dominant actually. He's the kind of dominant protagonist you'd see in like something written by a woman or something. That's another thing that's pretty rare I feel. I guess it helps that she is completely willing.
Actually this is making me wonder if at least one of the writers is a woman, because now that I think about it, describing both Minao and the protagonist personalities, the whole game feels like it's got that shoujo touch. It's almost like an otome game from the male perspective.
