Karaoke. Not a bad choice for a totally-not-a-date. I see she's trying to dip her toes into the water without committing to an answer. Testing the waters to get a feel of what it's like because IMO she's honestly unsure. Fair enough, seems in character for Shia. I like that she's a fairly complex, rather realistic character that can't be easily boiled down to the usual romcom character archetypes like tsundere, kuudere, dandere, yandere etc.
