JTBC's 10th anniversary special project 'Sigma: the myth' (played by Lee Jae-in, director Jin Hyuk, abbreviated 'Sigma') was the Existence of Questions in the Teaser Poster, and 'Sigma' was Kim Byeong-Cheol.
On January 8, a three-person Teaser Poster was released with a question of Han Tae-sul, Gangseo-hae (Park Shin-hye), and an unknown question about the world to save the world a month before the first broadcast. Since then, there has been a stir among viewers about who is the unknown presence hidden behind the silhouette. In fact, there were various hypotheses such as "Cho Seung-woo from the future is a sigma" and "the third person".
Even after the first broadcast, Sigma rarely appeared, only the fact that he was aiming for a tactic was transmitted through the West Sea. And in the last six episodes, finally Sigma's face became public release, and Sisyps released a surprise Public release of Sigma Teaser Poster's 'Face ON' version.
Sigma, who is looking down at our world with an unexplained face, first creates a cool tension with a much more eerie look than she imagined by looking at the silhouette. The fact that his cold life is heading toward Han Tae-sul is a creepy point. Even 10 years ago, his brother Han Tae-san (Huh Jun-seok), who had a strange sound to Tae-sul such as "Constraint Bureau", "Doaching" and "Other Existence", already knew his Existence. It was Taesan who witnessed the moment when Sigma, who was a smuggler, had just arrived at the present, and there were various risks to the future Taesul, such as photographs of Taesul in his hand and conference snipering. Sigma had been hiding in the world since then and watching the tactics.
So why is Sigma watching Tae-sul? Until now, it is assumed that it is due to the time machine, the "uploader", that Tae-sul made it, but it is not known exactly. Sigma, whose face is still buried in the darkness as much as the face hidden in the black shadows more than half, is creating a new mystery as soon as it reveals its face.
“Finally Sigma’s face was released public,” the crew said. So far, I am watching the tactics from behind, but since then, I have gradually begun to show my true color, and Taesul and the West Sea will be sucked into a larger vortex. “I would like to ask for a lot of attention to the future story of how Sigma’s appearance will stir up the Sisyphs journey of her “strong” partner.”
Sisyps is broadcast every Wednesday and Thursday at 9 p.m.
