This manga was never that good to begin with: slap stick humor, pretty typical drama, Suzuka being an absolute cunt.
But it all clicked at one point for some reason, the cringeworthy moments and mistakes that our protagonist would make, the slight and occasional transformations that Suzuka make (and no she's not really a tsundere, more like a complete tsun and then a complete dere, so no), and most of all, how soothingly and seamlessly the sports backdrop was weaved into the rather melodramatic plot. Thus this made not only the plot all the more engaging for us adrenaline junkies but also the conclusion all the more powerful. Perhaps it was a romantic ending, an unrealistic antithesis to the brutal suffering that our protagonist had endured. But it wasn't. Because Suzuka was still a cunt (though a nicer one, if even possible), our protagonist still an airhead, and just like the manga stated at the end, everything was still pretty much the same when compared to their times in HS.
And I think I like that. It didn't feel forced or anything-- no tragic ending nor complete disaster had to accompany the wholesomely organic slice of life feel and vibes that the manga had given off throughout its entirety. I especially loved the cheesy, albeit warming, foto of the couple with their friends and well ex's in the wedding photo. I also read the special but having the final moment be encompassing of a captured moment in time-- friends having a good time, uniting despite past hardships-- pays a strong homage to what the manga was really all about from beginning to end.
