This movie is more of like a heartbreaking reality of life because sometimes things you expect wouldn't always turn out as good as you imagined. I was heartbroken when Taeshik fought with his son Seojin in the streets because of how he was blaming himself because he saw himself as the poor worthless dumb father. I was so heartbroken because he was TRYING, gets beaten up every day just for 10k won and in the end everything won't be worth it because it gave him serious damage. Sadly things like these do happen in real life, I love how everything here shows the genuine side of every people. From happiness, struggles and success. And about the ending, they both deserved to win but we know there is always a winner and a loser.
