Although the day is ordinary, it is also full of sadness and sweetness. By mistake, he got a job in a water conservancy company and met a cold Japanese woman, Kyoko (Hiroko Berghauer). He was so attracted by each other's exoticism that they fell in love and soon separated from Kristen. But when living with oriental beauties, he misses Kristen more and more because of the huge cultural differences.
