"Shark" Son Ye Jin finally finds out about Kim Nam Gil's real identity.

June 25, the 10th episode of the KBS drama "Shark" featured Jo Hae Woo discovering the real identity of Kim Joon (Han Yi Soo/Kim Nam Gil) and his relationship with Han Yi Hyun (Nam Bo Ra).

Jo Hae Woo calls Kim Joon out to the park. She hands him some beer and brings up the subject of her childhood friend Han Yi Soo. Jo Hae Woo tells him about losing Han Yi Soo to a fatal accident and then later hearing from an old man in Okinawa, Japan that Han Yi Soo is still alive.

Kim Joon replies very coldly, "What is the reason you are telling me this?" Jo Hae Woo asks, "Is your original name Kim Joon?" She continues, "The reason I am trying to get close to a truth even when I don't want to is because I want to find Yi Soo."

Kim Joon replies, "Why are you trying to find Yi Soo?" Jo Hae Woo answers, "Because I want to stop. I know. I know that Yi Soo wants me to come to him.. and that he wants me to stop him."

At the end of this episode, Jo Hae Woo sees Kim Joon running into Han Yi Hyun at the 44th Anniversary Party at a hotel. Jo Hae Woo had been keeping a close eye on Han Yi Hyun to see if there were any men watching her. As Jo Hae Woo predicted, Kim Joon and Han Yi Hyun begin speaking to each other as if they have already met before. Later, Jo Hae Woo asks Han Yi Hyun, "Is it someone you know?"

Han Yi Hyun answers, "He's a customer that comes very often." Jo Hae Woo then becomes sure that Kim Joon is Han Yi Soo.
