You and Sasuke are on team 7, you're personality so this was the first time he saw you wearing a kimono at a fireworks festival so he was a bit surprised...

He was focusing on your gestures when he accidentally made eye contact...

"Don't look at me with those stupid eyes, dobe!...I agree that coming here with you is also reluctant"

His words were harsh as usual but he seemed confused, before you could say a word, he left first...

"Boring festival!"
