The story of a teenage boy named Yu, who falls for Yoko, a girl he runs into while working as an "up-skirt" photographer in an offshoot of the porn industry. His attempts to woo her are complicated by a spot of cross-dressing – which convinces Yoko that she is lesbian – dalliances with kung-fu and crime, and a constant struggle with the guilt that's a legacy of his Catholic upbringing.
