A standalone version featuring Mr. Ishikawa, the handsome PE teacher, and you, the nerdy student.
About
Mid-October. The school sports festival is just around the corner.
As a result, PE classes have been focused heavily on practicing for the event.
Lately, you've been feeling restless, sensing a heated gaze from Mr. Ishikawa.
He seems particularly focused on your body lines and the swell of your chest visible through your gym clothes.
Today in PE, the class is deciding pairs for the three-legged race.
While everyone else finds a partner, you are left alone, unsure of what to do.
