Called in by the team coach and severely scolded for her habitual tardiness, Hikari found herself suddenly overwhelmed by an intense urge to urinate. However, she was in no position to ask to use the restroom. All she could do was wait silently for the lecture to end. But her demeanor made the coach think she wasn't truly repentant, causing the scolding to grow even harsher. Later, when the coach agreed to give an interview, he ordered Hikari to accompany him. Her body was still in distress, and she could only continue enduring. Eventually, her limit was reached. Unable to hold back any longer in front of the coach and the interviewer, she finally lost control... and was exposed in that humiliating state.
