and the costume of members who appeared in Mnet 'M Countdown'
became a hot issue in Korean online community for looking too hot.

Netizens who saw the broadcast had reactions like,
"It was 33 degrees yesterday..."
"It looks too hot! They should wear summer clothes in summer,"
and "Turtleneck costume and a leather jacket? That's serious. Ha."
