Saw a YT story in this & decided to watch this since the actor Gong-Yoo (Also from Goblin) was the one who pushed to make this film happen.
This is not a review but actually a recommendation as to make everyone aware that these events actually happen and how we react to each situation can actually help someone or even change their lives.
Not gonna try & spoil this for you if you wanna watch it but this film is based on a real life story that happened in South Korea. The film was released in 2011 & received worldwide recognition I guess not because of the quality of the film (which is good btw) but because the story actually happened.
