"Please choose your favorite student..."
One night, overworked teacher Sasaki, buried in overtime, is suddenly confronted by something called the "Guilty Hall."
Standing before a row of shoe lockers transformed into selection panels,
he assumes it’s a dream and, jokingly, selects one of his students.
But when she appears in the classroom at midnight,
she glares at him with embarrassment and mutters with a foul attitude:
"Let’s just get this over with. Don’t bother trying to hold back."
A forbidden relationship between teacher and student...
Welcome to the "Guilty Hall," where all is permitted—
or so it seems.
