I just watched the movie a few days ago. Loved it and well had to do this video from the movie 'cause I didn’t found info on the OST. This actually like the last 7min of the film. If you have not watched this movie look for it and watch it. It is really good. It is about 5 couples and their relationships. It is an indie movie. Give it a try.
Music from Korean movie Come Closer 2010.
Don’t know the song or performers name. If you have any info regarding this please DO send Thanks.
