When night falls, the hospital takes on a quiet stillness, in stark contrast to the daytime bustle. Amid this calm, patient Takahashi continues his harassment, tormenting the nurses with lewd behavior. Today, he calls Chisato to his room to bring a urine bottle, then suddenly exposes his cock and plays a prank on her. Startled, she’s unable to empty the bottle and ends up sitting on the bed, forced to talk with Takahashi. As they converse, Chisato casually mentions, "This hospital was built on a graveyard." Hearing this, Takahashi visibly unsettles. Sensing his fear, Chisato seizes the moment to get her revenge—turning the hospital’s eerie past against him, blending history and the present in a chilling game of psychological payback.
