Is there anything more powerful than the desire for revenge? Maybe only love.

Those are the clashing dramatic elements that are expected to create an exciting storyline in the new KBS drama Shark. A revenge story in the tradition of "Revenge" and "Yawang," "Shark" will tell the story of a man who loses his father to the family of the woman he loves.

When the woman's family also tries to kill him, revenge temporarily takes precedence in his priorities. To take that revenge, he will go so far as to change his face and identity. But the one thing he ultimately can't change is the love he feels for the woman whose family he plans to take revenge on.

This week two new members joined the cast.

A few weeks ago it was confirmed that Son Ye Jin would play Jo Hae Woo, the beautiful daughter of the Gaya Hotel Group. Kim Nam Gil agreed to play Han I Soo, the owner of Giant Hotel.

This week, it was confirmed that Ha Seok Jin is going to play Oh Joon Yeong, Jo Hae Woo's fiancée. Also, Lee Honey has signed on to play Jang Yeong Hee, the assistant to Han I Soo.
