It can be both! Nino's first confession certainly came off that way to me long before I was a Nino guy (hell, I was singing Miku's praises until late March), but the confession should in theory be one of the major high points of a romantic series, drama or comedy. The wedding or actual pairing up is usually *the* climax, but the confession is one of the most important steps along the way.>>187794750
I've read plenty of shojo series. The main confessions manage to be both sweet and heartfelt and impactful quite often (unless the guy is an asshole who goes for the asshole confession, which has its own type of impact).
This confession is basically an afterthought. If anything, the way it played out, especially with the alleged Bakemonogatari parallels almost made it seem like a parody or send up of the main girl confession rather than the real thing. It had all of the right motions and lines, but none of the impact.
Posting my response here because the other one is about to die off.>>187794782
Well, you can use how things played out in chapter 67 as a start, plus probably have some more resolution to the Ichika drama. It would have gone a lot better if she hadn't run off after what happened in 80. Or if Fuutarou had both been more eager to track her down--and succeeded. Negi says he planned this series, so regardless of whatever in universe justifications you can give, it probably played out like it did for a reason--she's not the one.
Imagine how much more powerful her confession would have been if it had played out like:
Miku: I love you.
Fuut: I know.
And THAT was the first time we'd ever heard that he knew of her feelings. It still wouldn't seal the deal for her by any means, but it would have given the scene far more power. The way this arc played out took basically everything that could have given her confession an easy significant impact and put it somewhere else. She needed something big and unusual to make up for that. She didn't get it.
