Please Find Her (2017)

Can you find someone whom you saw once in the city with a population of 10 million people? A young man from Netherlands, Jan, flies 8000 km to Seoul in search of the girl he fell in love at first sight. He wanders into Itaewon, neighborhood known for its large population of foreigners and diversity, and meets unique Koreans, such as Jeong-nam, the legendary owner of restaurants in Itaewon, an oddball named Man-doo, and his beautiful stewardess sister, Ha-young, who go out of their way to help Jan find his love.
