Actually neat to see Synesthesia that isn't tying color to sound, but something a bit more "off the path" like this.
Also very cool to see her not fumble herself back down and commit to telling off the jerk who took the headphones. Whatever precedent it sets among her classmates, it should have been clear to everyone present that kid was in the wrong, so hopefully she can weather whatever comes after, now that she has Hiro-kun also looking at her favorably.
Already a pretty fantastic start. Excited to see more.
