'Descendants of the Sun' season 2: Sequel not possible

The Korean drama wave seems to have taken over the world. And with the latest hit, "Descendants of the Sun," it looks like the trend isn't going to end any time soon. The Korean drama just recently aired its final episode, but due to its immense popularity, fans are wondering if a sequel might be in the cards.
"Descendants of the Sun" reportedly closed its run with a particularly open-ended episode, making fans speculate if that was an intentional move to make room for a second season. Plus, the drama got consistently high ratings throughout its run, which means that a sequel won't have a hard time adjusting to a new audience. Rumors of a continuation have been rampant online due to this, however, things are not looking so great for hopeful fans.
According to reports, one of the scriptwriters, Kim Won Suk, has quashed the rumors of a possible second season. The writer explained that he is already satisfied with how "Descendants of the Sun" turned out and that the story has been told. According to Kim, his next plan is to write a historical drama or something that caters to a more adult audience.
It seems that the lack of a writer is not the only thing that will hinder "Descendants of the Sun" season 2 from coming to fruition. The main cast of the television drama may also be unavailable due to their schedules. The success of the show may have catapulted its stars' careers and a sequel might be hard to film with conflicting schedules.
However, there is the possibility of a sequel being shot with an entirely new cast. This is not new for Korean dramas as it has been done before with other shows. However, its ratings might suffer due to the lack of familiar faces, like Song Hye Kyo and Song Joong Ki, whom fans have come to know.
Regardless, fans remain optimistic about the future of "Descendants of the Sun," even if it means settling for a special episode instead.
