A man conducting an intimacy experiment monitors the physiological responses of his male subject. As the session begins, the subject struggles to suppress his physical reactions, expressing shock and confusion at his own involuntary arousal. The experiment concludes abruptly, leaving the researcher alone to grapple with his intense and unexpected personal reaction to the subject. He questions his sexuality, confirms he's not attracted to men in general, and privately admits his reaction might be specific to this one individual—a realization the subject's sudden arrival at the bathroom door underscores as unresolved tension.
