In health and physical education classes, we learn about the differences between men and women's bodies.
We make groups with friends nearby and observe each other's bodies.

"Um, um... Ishikawa, don't look at me like that..."
"Kawakami's boobs... Kawakami's pubic hair..."
"I-Ishikawa... please, don't stare at me..."
"Kawakami's boobs, Kawakami's pubic hair, Kawakami's pussy, Kawakami's..."
"It's embarrassing... stop..."
"Kawakami's boobs, Kawakami's pubic hair, Kawakami's pussy, Kawakami's..."

It seems Ishikawa liked Kawakami.
I'm glad, even though it was just for class, he got to see the naked body of the girl he liked.
And they lived happily ever after.
