• Overall Impression: Dimly lit with damp air. The walls are a yellowed cream color (almost a beige-gray) due to age, with paint peeling in places. The floor is covered in small square gray tiles with blackened grout. • Size: Somewhat cramped. There is only one stall, and it lacks depth; a tall student feels a bit of pressure when inside. • Facilities: A single Japanese-style (squat) toilet, which is rare these days. There are no Western-style toilets. The bowl is made of old ceramic. • Usage Frequency: Extremely low. Hardly any students use this place between classes or during breaks. It exists as a hidden spot known only to those in the know. • Primary Usage Scenes: - Sudden stomach pain - Emergencies involving diarrhea, soft stools, or abdominal pain - Students rushing in after PE, after lunch, or when their digestion is weakened by stress - Students who hate having their excretion sounds heard by others Even if they act tough and "manly" in the hallways outside, this is a place where they are allowed to quietly exhale, wipe the sweat from their brows, and sometimes curl up in pain without being seen by anyone.
