Mea, a popular girl living her best and carefree life every day,
suddenly finds herself at risk of repeating a year because of her overly laid-back attitude. Panicking at the thought of being in the same grade as her juniors,
she’s encouraged by the “principal” to join a school volunteer program. Reluctantly, Mea joins—but as expected, she starts slacking off…
only to end up in an unexpected situation. She finds herself in the territory of filthy old men—
a world where her usual common sense no longer applies.
