Happy Boys (2007)

Synopsis:
This goofy but playful comedy-slash-drama starring Seto Koji, Kamakari Kenta, Kato Keisuke and Shindo Gaku, follows the exploits of five handsome young men—each with their own hidden talents—following their dreams to become professional butlers. The shitsuji kissa (butler cafe) Lady Braganza, was founded by owner Shibukawa-san, with one purpose only: to provide their guests with true hospitality, which is, apparently, lacking in modern Tokyo. Also on the list: to help their female clientele with problems of the heart. As the Happy Boys come to learn, by resolving the worries and problems of others, they themselves will also grow.
