Same. The AixChie one doesn't bother me because they don't actually interact, they just walk by each other without even a glance, so it has no impact on what was actually shown at the beginning of the manga.
HarukaxKanae, onthe other hand... They are shown has having interacted before, in a way that should have sticked with Kanae, How is it that she didn't remember Haruka as "oh, is it that girl from the vending machine ? We even ended up in the same class ?"
Sure, Haruka has a different hairstyle, but feels like they should remember that interaction as their first.
