Character Arc

Lee Gyu-tae is a supporting figure caught up in the widening fallout once the red lines make hidden connections impossible to deny. Like many in the series, this character experiences the phenomenon less as a mystery to solve than as a force that exposes private life to the harsh light of public opinion.

Their storyline illustrates how quickly a society built on discretion can turn to suspicion and judgment when everyone's connections are suddenly visible. As the crisis deepens, Gyu-tae becomes one of the threads linking the personal cost of exposure to the larger investigation at the heart of the show.

The role highlights the series' central theme: that the collapse of privacy reshapes ordinary relationships and forces people to confront how they are seen by others. (Character name, casting, and details flagged for fact-check.)
