But Akari was never portrayed romantically with anyone and that's why it was enjoyable as slice of life/seinen story ... It was never a love history and I doubt anyone wanted that, just like with Amanchu.
One of Akari's friend had a crush with a boy but that was established very early... Then again, I wasn't around during the time Aria was serialized.
It is sad to drop the manga at this point because of the sudden change in direction but that shows how bad it was handled.
I was just discussing that. Other than Aika and Al's relationship,which was largely presented in a very low-key way, Akatsuki's obsession with Alicia, and President Aria's unsuccessful courting of President Hime, there were zero on-screen romances or even close to romance among the main cast. Alicia's marriage doesn't count since that literally came out of nowhere at the very end, mainly as a device for Akari to take over the business. There wasn't even subtext that I could find, and believe me I looked for it.
I suspect in the case of Amanchu, the author wanted to do more of that idealized "close female friendship" stuff and took it into subtext territory without even meaning to, and got blindsided by people shipping the characters.
