■Story
Kobayashi and Kasuga used to play at each other's houses, but as time went by and they grew older, they grew apart.
One day, Kobayashi arrives at school just in time and bumps into Kasuga.
Kobayashi is embarrassed to walk to school together, so he turns back the way he came.
He decides to retrace his steps to avoid her.
After school, Kobayashi is assigned to clean the gym storage as a punishment for being late.
For some reason, Kasuga ends up helping him as well.
While they take a break, they start talking about old times.
Kobayashi remembers having sex with Kasuga in the past and feels awkward.
They try to leave but find the door locked, trapping them inside the gym storage.
As the gym storage gets hotter and hotter, Kobayashi takes off his shirt, and Kasuga follows suit.
Kobayashi gets flustered seeing how different Kasuga's body is now.
Kasuga then confesses she really needs to pee.
Hearing this, Kobayashi looks at the bottle in his hand...
