"Yoo Danee, Byun Baekhyun, Do Kyungsoo, Jung Eunji and Park Chanyeol. You all must be in teacher's room right now."

The voice of their principal in the announcement.

Danee makes a straight face because she knows she was not wrong for the incident last week. Chanyeol throws a look to the windows. 
Baekhyun immediately took off his headphones. Kyungsoo is playing alone. Eunji is swallowing saliva and sigh.
