Drama Storyline

I just finished watching the drama from episode 27 to 35(last). This drama name is castle. I just too eager to know the entire storyline of the drama. 

In this drama, I like to watch 2 characters. They are 晴川 and 四阿哥. Indeed they are very attractive. Sadly both of them are not together eventually. 四阿哥 is a cool man. I like to watch the scene that he hugged the girl from her back with force. Wild and power. I like it.
