lawl, imagine that all we have seen of the actual wedding is w.e there was in the first chapter and the one panel in this chapter, that's it.... like holy hell, did Yotsuba even win? we haven't seen anything with Fuu and Yotsuba as a couple: kissing, hugging, hand holding, dating... just being close to each other... anything! No matter which girl won, I don't buy the relationship cause nothing's been shown: show not tell is a thing for a reason
now instead of any of that, Negi thought to waste chapters on stupid drama and BS, itsuki's dumb arc, rushed dad arc and so on -_- even the one date we got was more about them talking their feelings than being an actual couple
then the wedding itself, maybe showing her walking down the aisle properly, them taking their vows, kiss, standing at the altar... nah, negi thinks it's better to waste the final chapter on this completely stupid game that supposed adults are doing :/ ppl like to say Negi is an amazing writer, but nah: this is just generic harem trash tropes right here, it's clear none of the sisters have gotten over Fuu despite it being 5 fcking years cause harem girls who lose can't have non-MC love lives -_-
and it doesn't matter that Yotsuba won, ANY sister who won but had this same post-confession chapters = garbage. The manga's been going down in quality of a long while now, but this final volume has been really terrible.
