Man, couldn't make a more milquetoast MC if you tried. Dude just exists. He has daughters, that's it. First of all, he has 4 teenage daughters and somehow he can't cook and his daughters have to do it for him. He can't control his students nor teach his class, yet again, one of his daughters has to come to his rescue.
One of the teachers ask him how he was able to afford that house on a teacher's salary. Of course, there is no merit on his part here. His late wife bought the house and he also tells how they will be paying for the daughter's education with her money. In that same scene, he tells the teacher how the oldest girl basically took over for him in many of his duties. He always says how it isn't easy, but he does jack shit when he's in the house. Dude can't even make popcorn. I swear he's useless.
The dev is perfectly aware of how useless the MC is, though. The MC asks the teacher "who's the parent here? Them or me?" and she says "if Izzy had something to say about it, it'd be her." It's honestly embarrassing to play as this mf and totally unbelievable that anyone could crush on him.
He has to literally ask permission to his daughters to see if they allow him to date. They weren't kidding, he really is no father. Either way, he dates the teacher whether you want him to or not and I don't like the teacher, but it's truly pathetic that he has to ask permission. As pathetic as it is, they do allow him to date her, BUT, under the condition that they get to "veto" the relationship. I honestly got second-hand embarrassment from that scene.
His daughters literally buy his clothes for him. Honestly, I could go on and on, so I'll just stop here, but you get the idea. Anyway, aside from the useless MC, as it has been mentioned before, the girls are like a collectible, they don't stand out as individuals aside from Isabel. Nothing to get you to like them somehow.
Also, there are only a few choices and some of them change nothing. You're asked if you should let Izzy know that her boobs are peeking out, but even if you choose yes, the MC decides all on his own that he won't say anything.
As for the plot, it's extremely mundane slice-of-life stuff. But slice-of-life usually has some extra sauce that makes it enjoyable, such as comedy. Here, however, it's all just mundane stuff like going to school, going to the gym, watching a movie, etc. Of course, the "extra sauce" here are the sex scenes, which are almost non-existent compared to the amount of content there is.
This game is also missing the corruption tag, although it's the opposite of what it usually is. The daughters corrupt you, the MC. The renders are fine, I suppose. Nothing too ground-breaking, but better than many that have clear errors and/or look grainy.
