Love Exposure (2009)

The story of a teenage boy named Yu, who falls for Yoko, a girl he runs into while operating for the sake of sin as an "up-skirt" photographer. 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.
