I expected it of Woo Bin - he could carry any kind of production - but this was unexpectedly really good. The humour started from 00.01 and didn't stop until the credits. The acting was flawless. I expected that of Woo Bin of course, but I fell more in love with him. I'd watch anything he does. The chemistry he has with his co-stars is, as always, exceptional. I like that they became good friends through the filming and credit their closeness for the success of the acting. They all really acted excellently. Kim Woo Bin's character was the funniest in my opinion. The character's personality and behaviour, interaction with others was fun to see and enjoy. As I said before, he was flawless. his scenes with his father was hilarious. Not to be missed. And his character at the end fighting scene had to be watch again and again That scene was too hilarious. This was a good film production for all the actors. The story made me remember my teens and 20th year. To do that meant that this movie succeeded in it's goals. I loved it a lot. There were munites that the story lagged, but that was few and far between. Nothing worth mentioning much I also loved the ending because it depicts exactly how most twenty-year olds end up. You don't know where you're going next but the point is that it's time to try anything and try getting your life on a good track - whether you succeed or not. The music was okay, not really memorable. But I would definitely rewatch for the Woo Bin , Junho, Haneul eye candy and the story of course, and the acting most definitely. There's loads of talent in this movie. I'd recommend this movie to any one who needs a laugh, needs encouragement, or battling unhappy feelings. Kim Woo Bin makes this movie so worth it. . Update: The music actually sticks with you, especially as it's in English. I woke up singing "When I was younger..." And it won;t leave my head.
