Say It (당신이 그것을 의미처럼)

The Park family own a well-known, highly successful law firm and are in charge of the Ryu, which is the equivalent of a Mafia.(Contradictory, much?)
They have long been rivals of the Seok (the Mafia that Woo Bin's family run.) But, due to the emergence of the Han, the Ryu and Seok have decided to merge forces. But there's only one key to forge the bond between the two groups: The headstrong Kana-Su and the Casanova Gangster, Woo Bin.

Kana soon learns that she can't run away from her problems –or the F4- forever, and that she is going to have to support all she goes against in order to protect what she loves.
