Soo Ah and her friends have Teacher Yang wrongly accused of inappropriate behavior, and the corrupt principal and parents are grateful for an opportunity to have him fired.
Yeon Doo has trouble remembering the cheer team's drunken night in. Principal Choi cracks down on finding the staff member leaking Sevit High's dirty secrets.
Cheer practice begins, but the team is put through more physical punishment than actual training. Yeon Doo and Yeol bond on a day out, upsetting Dong Jae.
