She seems nervous but it's understandable since it's her debut performance. And her vocals are weaker, thinner from the studio version.
The song is still the bop of the year though
She seemed nervous so I was very surprised to see that she sung live! I thought her voice would sound a little weaker live but she pulled it off. It was a great performance but there's still room for improvement but serve those live vocals
she needs to go on tour right after the EP drops to work on her stage presence (and maybe work on her pitch a little), but it wasn't that bad for a debut performance.
