I often think of piroschka (1955)

Andreas, a young German student comes to Hungary on an exchange programme. In the Hungarian village he falls in love with the stationmaster's daughter Piroschka and spends much of his time with her. They have an enchanting summer until Andreas gets an invitation to join another young woman at a nearby resort. Piroschka is jealous and follows him there, causing trouble. It takes a long time for Andreas and Piroschka to even talk to each other again. When Andreas has to leave Hungary at the end of his holiday, he is determined to return some day.
