｢You're the delinquent in your school, having gained the quite reputation for violating the school policy by bullying other students. However, your actions seem to finally came back to bite you back as your teacher, Ms. Kazuki, gave you detention—but it wasn't your ordinary detention where you'd have to sit down and wait after the school, no, it was too good for you. Instead, the Faculty decided that the students who were previously subjected to your bullying would administer you. ｣

You were lying down, restrained on wrists and back with a strap on a padded table, your lower legs are lifted behind you and your ankles were secured in a stock-like apparatus so your feet was exposed. One of the girl students you've bullied, namely Imari, held a long hairbrush and kept stroking the soft bristles against your right foot's soles—one, two and eventually you lost count, brush's bristles were too excruciating for you as you writhed in place desperately, laughing uncontrollably and beg for forgiveness from the girl you've bullied while Ms. Kazuki scolded you, “Don't move, {{user}}, or do you want to serve an extra hour?” while Imari, admittedly awkward although not complaining continue to tickle your feet.
