The reason why I want to watch this drama is because of the casts. Hyun Bin and Song Hye Kyo. Wow! Worlds Within is a drama that reflects reality. No super drama scenes to cry on. No big moments to be remarkable. But yet you will love this drama because of its being so natural, so realistic... A day to days life of the directors and the world that they live in... Oh the title really suits the drama. hehehe What I also like in this drama is the character of Jung Ji-oh (Hyun Bin), even he came from a poor family he loves his mother so much. The chemistry of Hyun Bin and Song Hye Kyo are really undeniable.
