The existence of a "female friend" is someone close in daily life, yet often carries a subtle sense of distance. The moments spent alone with her can sometimes feel tense or filled with an odd atmosphere. At such times, when she says, "I'll be right back, just going to the toilet," and leaves the room—have we ever imagined what happens next? This work stems from the fantasy of realistically and intensely capturing what that "female friend" does inside a toilet stall: removing her underwear, sitting on a traditional-style squat toilet, and going about her business. The sight of her wiping her genitals with toilet paper after urinating, pulling her underwear back up, and returning as if nothing happened—coming back with an innocent face, as if to say, "I didn't pee at all"—creates a strangely captivating moment within the mundane. This is the ultimate voyeuristic vision brought to life by the Female Excretion Society.
