The new Niyomsil School principal unveils plans to cut clubs that aren't performing to her standards and Gun's music club tops her list. Gun runs for student body president as with it comes the power of choosing which clubs are pulled, but he's beaten by the principal's son Tinn. Gun's next course of action is to try to raise the club's standing by performing well in competitions, but he's fighting time and Tinn's seeming determination to see them fail.

The music club's no dating policy comes into question when Yo meets Nook on Tinder but uses Tinn's photos instead of his own, out of fear of the club rules.

Chinzhilla, accompanied by Tinn and Thiw, take a trip to the beach to find inspiration for their music. However, when they arrive, Yak has other plans for them in the form of an intense rehearsal schedule.

With Tinn, the music club takes a trip to a temple. On the way there, they encounter a closed off road and are forced to walk with Por injured. Smarting from their Hot Wave loss, the heat and the exertion creates tension among the club members. Principal Photjanee is fixated on learning the truth behind Tinn's closeness with Gun.
