90s Moive, Non English, about a boy who goes to stay at a farm

Trying to find name of a movie I saw once back in the 90s, it was not an English spoken movie. It was about a young boy who lived in city and loved playing a video game about a warrior who saves a princess from a monster. His mother sends him to stay with a family at a farm, where he starts to fall in love with the older daughter who he on daily basis helps do chores around the farm. Later on her boyfriend/fiance comes to visit and the boy starts to have funny dreams/fantasies where he is the hero who has to save princess (the daughter) from the monster (her boyfriend).
