Saito is a playwright who used to write screenplays in TV dramas and is now a teacher in the screenwriting course. Twenty years ago, Daisuke Uehara, a good friend when he was studying abroad, was about to marry Lola, an American girl. Daohsiung came to Los Angeles to attend his wedding. Daisuke went to the airport to meet him and drove with his old friends. Daoxiong wanted to visit the wineries, while Daisuke wanted to enjoy his last single time. Daoxiong learned that his secret crush when studying abroad, Yuko Tanaka, lived in Napa, a famous wine-producing place. He visited the wine store where Ma Youzi was located, but failed to meet her. The next day, Daoxiong ran into Ma Youzi in a restaurant, and Daisuke took a fancy to Ma Youzi's friend Menai. The next day, after the two men finished their SPA with the discount coupons sent by Menai, they split up. Daisuke went to pick out the wine for the wedding, while Daoxiong pretended to be Ma Youzi's husband and went to other wineries with her. Five years ago, Ma Youzi and her husband ordered wine in this winery. Ma Youzi mentioned the past: she has been living in Japan since she married the boss of a big enterprise who owns a department store. She divorced five years ago and finally got her present life. Ma Youzi held a small party at home. Daoxiong cooked his own specialty, while Daisuke made his own specialty.
