Chaeyeon apologizes for leaving EXO concert early and eating during the concert

Chaeyeon is in the same bowling team as EXO'sChanyeol, who invited her and all the other members of the bowling team to EXO's 'EXO'r'DIUM [dot]' concert on the weekend. However, the bowling team's attitude during the concert became a subject of controversy, as the entire team ate during the concert (there is no food allowed in the stadium during the concert), allegedly belittled the talk during the concert, and left before the concert had ended.
