The blockbuster drama KBS IRIS has ended, leaving many mysteries that viewers are dying to find out. We foresaw that the final episode would reach the 40% ratings mark, which it did. Wednesdays episode had a rating of 35.0% and Thursdays episode reached 39.9%, which is two-fifth of the people in Korea watching. We reported earlier that the drama would have a sad ending, instead of the originally planned happy ending. I have to say that I was on the verge of tears while watching the final episode, but at the same time, I was irritated that the drama left so much to think about. The two main characters, Kim Hyun Joon (Lee Byung Hun) and Jin Sawoo (Jung Jun Ho), were both killed off. The IRIS members had turned on Sawoo, making the two former friends work together. Unfortunately, Sawoo was shot by an IRIS member, leaving Hyun Joon and Seung Hee (Kim Tae Hee) in tears, watching him slowly die. During the final minutes, Hyun Joon was driving, when he was unsuspectingly shot by a sniper. It showed the car window broken, and Hyun Joon bleeding in the head. He had stopped right in front of the lighthouse, which was where Seung Hee was standing, who had earphones on. She did not see Hyun Joon bleeding in the car nearby, and did not hear the gun sound either. The drama then ended with Hyun Joon looking at her and thinking about the past, showing flashbacks from the earlier episode. For those of you who saw this scene, I know that you wanted a clear explanation on everything, as we do not know much at all. Who killed Hyun Joon? Why couldn't Seung Hee see someone bleeding right in front of her? Who is Mr. Black? I am hoping that all these will be explained in the upcoming IRIS 2.
