Artist's commentary
E-Even sensei... can do... this much...!
Mami-sensei is sent out to keep track during a sports test.
Riku: "It's Mami-chan-sensei! Yahoo!!"
Misaki: "Yahoo."
Sensei: "Should you two be on a break right now??"
Riku: "We're pretty much done~. Anyway, you look like a PE teacher in that tracksuit, sensei!"
Misaki: "I think it looks good on you."
Sensei: "D-Does it really...?"
Riku: "Though I doubt Mami-chan-sensei can even handle the horizontal bar lol"
Sensei: "...Mukuu. Just watch me!"
.........
Eventually, Sensei's whistle hit her in the face halfway through a full swing,
she got startled and let go of the bar, fell on her bottom and ended up half in tears.
