Kim Joong Ki Park Joong Ki and Song Boo Geon Koo Kwang Soo are absolute eye candies for me and I have been loving them since the 1st season.
In the last 2 eps, they basically tried to solve the puzzles of this season plus gave clarifications about some things which were left on hang in the s3.
Now that the Circus Man's journey has come to an end, I look forward to a new journey into Kang Kwon Joo's superhuman hearing abilities.
