In essence going the LN naming route with the title was the wrong choice and it probably would have been better titling it something like "A Story About Dumb People and Their Relationships" or something because that's basically what it is. But I'd rather have well built and fully fleshed out cast where I actually like and care about seeing their stories than having an endless stream of shallow fluff and glurge.
I agree with this take except for the last section because not even a title change can get over the shallowness of people who complain about the extended cast getting focus. Even in a manga like "Komi can't communicate," where the first chapter sets the goal of making 100 friends people still complain about the extended cast. You just have to give up on them, they can't be helped.
As for everyone else who thinks this story is "milking" itself, I don't even know what people want from Romcoms anymore. I know everyone is different but don't people complain when stories end with the couple getting together. A relationship isn't just a goal that's completed when you get together, it grows, it may end who knows. And as for this joke they keep using, they get to keep using it because these characters grow and change every time it happens.
