If chopping your story to pieces with a blunt axe is an acceptable way to be solved and done, then I agree. I still think that ~110 would've been the perfect point to end it, a couple of epilogue chapters to show Yuzuki moving on and stuff, and everything wouldn't be amazing, but kinda decent I'd say. Breaking up with Asuka and getting together with Yuzuki was the low point of the series, or the boiling point of idiotism depending on persepctive, and ending it there would've left a pretty bad aftertaste. Not that I like the lack of consequences, but it at least feels better now. You can't really salvage this trainwreck anymore, might as well make it somewhat less annoying.
Although the last 50 chapters of pretty much nothing probably work in favour of the blunt axe, I guess.

Should I cook? Shouldn't I cook? Is this a cooking manga? Don't know, but hey there's nothing else happening anyway. And Haruto nearly summersaulting of the bed because he can't touch his girlfriend's clothed breasts has to be some of the most ridiculous shit I've seen in manga. Hilariously enough I think Akari actually is ahead in terms of intimacy with Haruto overall, despite never getting the many scenes she actually deserved.

Hahaha, you kiddin' me? What the heck is up with that? I'd dump her dumb ass in an instant for that. Not enough that she made him (and everybode else I'd guess) worry for 6 days to the point he thought she went missing, no, she also gets back and is still acting like that. Considering stuff like this is her most prominent character trait, you really have to question why Haruto even loves Yuzuki. And Asuka even has to cheer him up, maybe the couple really deserves each other.
Well, obviously a small epilogue after it would had been ideal, but it didn't need more than an extra 5-10 chapters to finish the story after they got together, there just was nowhere else to go after that, as the remaining chapters go to show.
The series last nearly as long after they get back together as everything else from before.
I'll say that after Haruto breaks with Asuka to go back to Yuzuki, they clearly deserve each other (thoughI still think Yuzuki is the worst of the two but that's lets not get into that).
