While Uta is resting in the school infirmary, exhausted from daily sadness, her homeroom teacher's colleague suddenly visits. He speaks gently, attempting to heal her emotional wounds, and his warmth initially seems sincere. Gradually, Uta opens her heart and willingly spreads her legs.

These places are no longer mere facilities, but arenas for their unchecked desires.
