P Kan couple (2005)

Trying to break out of his shell, he forms a baseball team to communicate with the people around him. He posts an ad for the team, “Frustrations” on the company’s bulletin board but no one joins him. Bito swings the bat alone for days until he meets a half-naked woman sunbathing on the grass. He is fascinated with the woman, Mitsuko, and they make love right there. After that, they get married but to Bito’s shock, Mitsuko refuses to sleep with him unless it is outside under the sun.
