Since his new movie just came out, let's look into more awesome roles Gong Yoo has had!
I first fell in love with him thanks to Coffee Prince, which is still one of my favorite dramas of all time.
He plays a rich boy who learns to work hard and care for others. He also halls in love with his coworker and doesn't really care that that coworker is a man (of course, he's not really, but still the fact that he doesnt seem to be freaked out by that is awesome for Korean media!)
Finding Mr. Destiny
He plays a detective that specializes in finding people's first loves. He's a little quirky and odd, but at the end of the day he's a great character! The film is great and I highly recommend it.
He plays an 18 year old trapped in a 30 year old's body and as you can imagine the results are hilarious.
