Ureshon!

A boy falls in love with a girl, who he witnesses urinating in public. Unable to confess, he is gifted with a deus ex machina when the girl suddenly transfers to his school. Never minding the coincidence, he immediately calls out to her, and is overjoyed to find out that she wet her pants the moment she saw him. Hijinks ensue as the two strike up a deal to partake in their darkest, most wild urine-based fetishes. While the two engage in water sports, DRAMA ensues as they begin to fall in love with each other instead and question the NATURE of PISS.
