At first, I only watched it because of IU, but watching the movie as a whole was worth it. Now I know why it's called Shades of the Heart

I recommend watching it if you watch Slice of Life kind of film or drama.

Your feelings will just be 'Meh', if you know what I'm saying, It can be boring for a lot of people, you may also get the similar feeling to a drama 'My Mister', when Ji-An (IU) is listening to Dong-hoon just walking his way from his work all the way to a friend's bar through the wiretapped phone but the feeling of getting to know different people's stories and their perspectives can be quite nice, whether a person is thinking that everything is moving quite fast or a person realized that he/she actually received a bad news sugarcoated in a good news
