nah - Asuka's been friends with Hina since...well, they were kids. And she had a front-row seat to her best friend turning down everyone who approached her with romance in mind, and be single-minded in her focus on running/athletics.
She has every justified reason to believe that Hina really didn't care about/want to date or do the SO thing, with literal years' worth of track record and evidence to back that up, and so she'd resolved to simply be her best friend and stick by her as the most important person to.
It wasn't until the literal MC of this title showed up in the present and said the exact same thing to Hina that everyone else had--all of whom had been rejected--only this time, for whatever reason, Hina actually didn't reject MC.
Which has both confused the hell out of Asuka, and probably (understandably) pissed her off.
