Nobita no Kekkon Zen'ya [English]

The movie starts with Dekisugi expressing his love to Shizuka, which makes Nobita cry (even though it was a rehearsal for a play in Nobita's school though Nobita thought that it could influence Shizuka to marry Dekisugi). He goes to Doraemon, asking him to take him to the future to see if he and Shizuka will marry.
