I was looking for something that would help me get past my sober feelings left by Moon Lovers and was watching a WHOLE BUNCH of trailers when I came across this piece of gold. Twenty is VERY funny, but only if you are in a certain type of mood. It is not a movie to watch when you're feeling a melodrama or serious movie. It is very sexually driven and laugh-out-loud funny. Do not watch with your parents. I repeat, DO NOT WATCH WITH YOUR PARENTS. I'm really close with my parents and we have open discussions about sex and other intimate topics, but it would be AWWW-KWWARD watching this with them. Anyways, the progression of plot was well done and well paced and I would just like to say that these dudes would be my ideal friends in real life. Movie was so entertaining that I watched it with my brother (who I'm really close with) the very next day.
***SHOUT OUT to Kim Woo Bin --- major eye candy --- his character was my favorite. His temper tantrum for continued allowance with his parents was really funny!
