Such a great feel good movie. Really light fun story, with a great cast, and set in the beautiful city of Busan. It has just enough drama to make your heart squeeze, and the characters and the relationships are developed at a great pace. The one night stand is a common rom-com theme, but I think what sets these movies apart from one another is the way they make that brief encounter meaningful. I think the movie was successful in adding depth in a way that makes the development in the story, particularly the characters' relationship, believable. Definitely worth your time!
