It's like everyday life in reality, school, band, the band break up, and one girl a korean exchange student be asked to join the band. The band called PARANMAUM, which means The Blue Hearts in Korean. I pretty much enjoy this movie, some people say its boring. But that is slice-of-life! and by the way i really like the main song Linda Linda Linda, its pretty good because it definitely sounds like Ramones.
You see the vocalist? Yeah Bae Doona, the reason i watch this movie haha. Her character is innocently funny. Well school, band, friends.
