Your review is not only inaccurate, it is also highly subjective.
As I recall, in the first chapter alone, it is possible to see any one of the three main girls topless (two for sure). By the end of the third chapter, there is at least one full-intercourse sex scene, with some variation depending on how you got there. I think there is at least one other sex scene which I haven't found yet myself. There is also a variety of adult scenes that don't have full intercourse.
But let's pretend that wasn't the case. Let's pretend this game had no sex scenes at all. It's still only chapter three. I've played lots of VN without any sex scenes in the first three chapters. So, saying it doesn't have "enough" sexual content is an extremely subjective statement. The review rules actually ask that you be objective.
You also accuse it of bad writing, without saying why. Now, to be fair, lots of people have said it has
good writing without going into specifics, but bad writing could mean so many things: bad plot, bad dialogue, bad grammar/spelling/translation, etc.
In an industry that has so many games which claim "your choices have meaning" and then don't live up to that promise, this is a game with many MANY possible paths, where your choices really do have a big impact on where you go and what happens. That walkthrough guide has eleven different ways of playing this game, and that's only scratching the surface. Different paths have different nudity/sexual content, and some of the paths have none. It's written that way on purpose, and the game does kind of warn you about that at the start, if you read the tutorial.
I'm sorry you were disappointed by your experience with this game, but I think you've misunderstood it.
