Wakaba, a college girl who longs for the青春 (seishun, or youthful days), decides to make her “college debut.”
On Halloween at age 20, she goes out in a school uniform costume,
and by chance ends up going on a date with a high school boy named Ikuto!

“If I were a high schooler too…
Would we have had a future together like this?”

Though she thought it would be just a one-day date,
due to “certain circumstances,” the two begin re-living青春 together!?

Taking on all those classic youthful situations together—
A fake high schooler’s second-chance, uniformed love story!
