Last Life in the Universe (2003)

A mysterious, obsessive-compulsive, suicidal Japanese man living in Bangkok, Thailand, is thrown together with a Thai woman through a tragic chain of events. The woman is everything he is not. He is a neat freak who keeps his dishes washed and his books neatly stacked and categorized. She dresses like a slob, smokes pot and never picks anything up. It's a match that somehow works, though. Slowly and entertainingly, more is revealed about the Japanese man and why he's suicidal and living in Bangkok.
