The prose in this VN is pretty average. For something so beautiful, I expected more from the writing team.
A lot of things happened that didn't make sense, and no, I am not referring to the situation the characters find themselves in. I mean their emotional and rational reactions and thought processes.
I mean no offense, but is the writer (or at least the one planning the scenes) autistic? Or is the MC supposed to be autistic?
It is extremely frustrating and uncomfortable to experience the story in his POV and none of the characters are acting normally. So I have to assume the writer is the one at fault, or it was intentional because they want us to experience what it is like being in an autistic person's POV.
I recommend you take a BIG step back and put on the shoes of your characters when writing them, their motivations, and so on. This feels like a single person who doesnt know how people normally interact is playing with them like dolls.
