I know I am way late to the game on this, but this is why we love Sunmi. This bitch can't be bothered. She sort of half-heartedly does the choreo in the group parts, but when it's her turn to do a solo she's like "fuck this noise" and just slumps around with her arms crossed.
"Yeah, I'll sit down early if I fucking want to" -Sunmi to the cameraman
She looks hot, though.
