Guilty Hole ～ Room of Guilty Pleasure follows Mamoru Sasaki, an exhausted teacher whose ordinary school nights take a surreal turn when a mysterious realm known as "Guilty Pleasure" suddenly manifests before him. The familiar rows of student shoe lockers warp into strange selection panels, and in a moment of disbelief—convinced he must be dreaming—he makes a lighthearted choice without a second thought. But the boundary between dream and reality begins to blur when a student unexpectedly appears in his empty classroom under the cover of night. Set within a forbidden space where all rules are said to be suspended, the story explores the uneasy tension that emerges between a teacher and student once an invisible line has been crossed. What unfolds in this hidden room of guilty pleasures is a relationship that neither of them may have been prepared for.
