It's really kinda crap that THE relationship that has been built throughout the whole manga, Satsuki and Akira, just does not get any showing not just at the very end but for the last 5 chapters.
I wasn't expecting a confession but there really should've been some sort of acknowledgement to just how valuable that relationship has been to Satsuki.
Instead we get all the focus put on Komachi for 5 chapters, who's presence has been more of a background thing for much of the manga, and an end entirely focused on her.
It's a real shame.
You have my sympathy.
On the bright side, I feel validated for dropping the manga dozens of chapters ago. (Checked back solely because I saw the [End] and wanted to know if I should give it a second chance.)
Not that I'm saying anyone shouldn't like the manga; if you like it, glad you enjoyed it. Just saying I'd have been one of the disappointed readers, too, had I stuck it out the end.
