One of the best korean movie I have ever seen. I love Kim Soo Hyun acting skills.
This is the best choice if you want to watch something at the end of the day, but do not want a series with long episodes. The storyline is amazing and I love the end as well, however I love happy ending this is not one of those movies where we got a clean happy ending, but it is alright.
So I would recommend it everyone.
