How will IRIS end? (warning: Major spoiler ahead)

With the impending conclusion to IRIS taking place over the next 2 days, the original happy ending has actually been rewritten to end tragically! According to a production staff, "The original ending was that Hyun Joon (Lee Byung Hun) and Seung Hee (Kim Tae Hee) will resolve their differences with each other in the end. They will then end happily ever after as Hyun Joon places the wedding ring onto Seung Hee's finger. But the ending has been changed recently after several meetings between the director and writers, with the decision taken to kill off Hyun Joon.." The original novel novel was that Hyun Joon and Seung Hee will end up together. But Taewon Entertainment had already said beforehand that they would film a different ending, with many netizens trying to second-guess the ending all this while. As for letting Hyun Joon die, many have offered their opinions. Some felt that the writers are hoping to create another climax with the death of Hyun Joon. Another said that since Lee Byung Hun had already declined to appear in the sequel, there was no point to let him continue living on. Other than the ending, there are still many questions waiting to be answered in the final 2 episodes. Among them include Seung Hee's real identity, Baek San and Seung Hee's relationship, the leader of IRIS, etc. All these questions plus Hyun Joon's death will become the highlights in the closing stages of IRIS. Stay tuned to see if IRIS can break the 40% mark.
