Not sure her hair would grow that much since middle school.
Also not sure I've heard that specific ambiguous line before.
Of course you have that kind of interruption. Because you couldn't have delayed it in any actually clever, reasonable, and/or original way.

Aaaaaaaaand of course the other girls interrupt right as Hanako is about to confess. Fool that I am, I still had a slight expectation that she'd actually get to confess. What an idiot I am.
I was hoping they at least would have a decent reason to delay it, but nope. Just the bog-standard cliché of having other girls arriving at just the wrong moment.
