Ok so my review scores might be a little biased I'll be the first to admit. But it comes from a place of love. I loved this manga and for the longest time I held it as the pinnacle of character writing and romance. It was a 10/10. But then the story hits something like chapter 180 and it just... isn't great. It slowly gets worse after the main character graduates high school. The author spends something like 2 years just wasting your time, creating bullshit plotlines that mean nothing and doing nothing.
But god even that couldn't take this below a 6/10 for an average non invested reader. It was still enjoyable.
But the last like, 30 chapters? Some of the worst shit I've ever read. Over the course of chapters 271-276 the author manages to more or less ruin the narrative she's been setting up for 5 years. Completely scuffed and irredeemably bad. Even if the girl you wanted won you can't say the writing was sensible in any way.
So I feel like I'm being generous with a 3 overall. While the sum of its parts, if taken individually might still be a 5 or 6, this is a romance. In my opinion, the ending to a romance is the most important thing, and if your ending involves undoing every bit of personal character development of every character in the entire story and just returning everyone to how they were in chapter 50... you did nothing but waste time and I cannot, in good faith, give a score any better.
Any enjoyment I've gotten over the past 6 months of reading this weekly was just freaking out by how much harder the author can botch her story.
