My memory of the manga is terrible -- partly b/c I read it several years ago & my memory is just... not always up to scratch. But partly also b/c I read the last few volumes hurriedly in bookstores, so... not really a retention-prone strategy.

That's a really interesting idea about Hatsuharu & Akito!!

(Also, Haru is a more minor character, but I had a personal interest in him b/c of his clothes & sense of style. :D )
