Eri, while heading for school, teaches the viewers the invisible chair and calf raises, in a train. Afterwards, she introduces them her friend, who thinks Eri and the viewers are a couple.

Back in Shizuno's indoor pool, Asami was about to train for her swimming competition at school, until Shizuno suggested that she needs to do her warm-up stretches.

Soon after, Asami, Eri, and the rest of the girls enjoy their bath time, while Eri gets more jealous when she notices that Asami's breasts grew a little more bigger.

After witnessing that Yū was jogging like Asami and Eri did, Shion massages her leg to relax. Then, Sakura appeared, and while teaching and massaging the viewers, Sakura and Shion fought over Yū.

After they finished warming up, and Andalucía tied Shizuno up and made her fall on the viewers, they all enjoy the tea made by Shizuno.

Yū was concerned about using her contact lenses rather than her glasses, so in order to relax, she does, while teaching the viewers, the Unilateral Push-ups and the Prawn Back Extension.
