| The Lie We Lived In Relationship Chart Explained: Who’s Who in the Korean BL Thriller Everyone Is Talking About. (Credits: Viki) |
A killer pretending to be someone else, a detective chasing the truth, a hostage caught in the middle, and a house packed with secrets. That is the chaotic setup behind Korean BL thriller The Lie We Lived In (거짓말이 사는 집), one of the most unusual Korean web dramas arriving this year. Mixing mystery, romance, crime and psychological tension, the eight-episode series throws viewers into a situation where almost every character is hiding something. If the title sounds suspicious, that is because nearly everyone in this story seems to be living inside a lie.
At the centre of the drama is Seo I Do, played by Kim Seung Beom. I Do is a professional contract killer sent to eliminate a target named Heo Dong Hwa. However, before he can complete his assignment, his boss unexpectedly changes the plan and orders him to keep Dong Hwa alive.
That alone would be complicated enough, but things become even messier when I Do is mistaken for Heo Dong Jin, Dong Hwa's younger brother who supposedly left for the United States years ago.
Rather than correct the misunderstanding, I Do decides to continue the deception. As a result, he ends up living inside a role that was never meant to be his.
Opposite him is Chu Tae Jeong, played by Kim Kyung Min. On the surface, Tae Jeong appears cheerful, friendly and perhaps a little too comfortable showing up unannounced.
However, beneath that easy-going personality is a determined detective investigating a much bigger mystery. He arrives at the house believing he is visiting an old friend, only to unknowingly step straight into a situation involving hidden identities and criminal secrets.
The drama's central relationship develops between Tae Jeong and I Do, creating a fascinating dynamic where one man is desperately hiding the truth while the other is professionally trained to uncover it.
The relationship chart becomes even more complicated when viewers meet Heo Dong Hwa, played by Lee Jeong Ho. Dong Hwa is technically the target who starts the entire story.

| The Lie We Lived In Character Map Explained: How Seo I Do, Chu Tae Jeong and Everyone Else Are Connected |
His connection to both I Do and Tae Jeong places him at the centre of the mystery. While he may initially appear like the victim in the situation, early previews suggest there is far more to his story than first impressions might suggest. In a drama called The Lie We Lived In, trusting appearances feels like a risky hobby.
One of the most important supporting characters is Choi Mu Gun, portrayed by Baek Dong Hyeon. Mu Gun is I Do's boss and guardian figure, making him one of the most influential people in the assassin's life.
He controls much of the mission and holds significant power over I Do's future. Whenever Mu Gun appears, viewers can probably expect tension levels to rise immediately. He is essentially the person responsible for keeping everyone trapped inside this dangerous situation.
Working closely alongside Mu Gun is Kentaro, played by Terada Takuya. As Mu Gun's trusted right-hand man, Kentaro acts as an extension of his authority.
While details about Kentaro remain limited ahead of release, his loyalty to Mu Gun suggests he could become a major obstacle for anyone hoping to escape the web of secrets surrounding the house.
Another intriguing character is Hyeon, portrayed by Lee Jae Jun. Hyeon is described as an admirer of Mu Gun, which immediately adds another layer of emotional complexity to the story. In a series already filled with hidden feelings, secret identities and shifting loyalties, Hyeon's personal attachment to Mu Gun could influence several key developments later in the drama.
Meanwhile, Im Jung Gyu plays Seong Jin U, a former high-school classmate of Tae Jeong. Characters connected to a protagonist's past often arrive carrying information, memories or unexpected complications.
Given the mystery-driven nature of the series, viewers will likely keep a close eye on Jin U's role as the story unfolds. The family side of Tae Jeong's life is represented by Chu Dae Seok, played by Joo Jeong Hyeon.
As Tae Jeong's father, his appearance helps ground the detective's personal story amid the increasingly dangerous events taking place inside the house. While much of the drama focuses on suspense and romance, family connections could prove equally important when hidden truths finally begin to surface.
What makes the relationship chart particularly interesting is how every major connection revolves around deception. I Do pretends to be someone he is not.
Tae Jeong unknowingly develops feelings for a man living under a false identity. Dong Hwa is surrounded by people with conflicting motives. Mu Gun controls events from the shadows.
Even supporting characters appear tied to secrets that have not yet been fully revealed. Rather than presenting a straightforward romance, the series builds its emotional stakes through mistrust, misunderstandings and the constant threat of exposure.
Director Son Tae Gyum, known for his work on Love in the Big City, has described the project as an exploration of two completely opposite men forced into the same space. That contrast is clearly visible in the lead characters.
I Do represents secrecy, danger and survival. Tae Jeong represents truth, justice and investigation. Naturally, putting those two personalities under one roof sounds like an excellent recipe for emotional chaos and terrible life decisions.
Early reactions from BL fans have been varied but largely enthusiastic. Many viewers are excited by the combination of thriller and romance elements, noting that assassin-and-detective pairings remain relatively rare in Korean BL productions.
Others are particularly interested in Kim Seung Beom and Kim Kyung Min's chemistry, with previews already generating discussion across social media. Some netizens have jokingly pointed out that pretending to be someone else's brother while falling for a detective sounds like the sort of life choice that could only happen in a drama. Thankfully for viewers, that is exactly why it looks entertaining.
With only eight episodes, The Lie We Lived In appears determined to move quickly, balancing suspense, romance and mystery without wasting time. For fans looking for a BL drama that offers more than simple romance, the series could provide an engaging mix of emotional tension, hidden agendas and unexpected twists.
The real question now is not whether the lies will eventually be exposed, but how much damage will be left behind when the truth finally arrives. Which character are you most curious about: the mysterious Seo I Do, the determined Chu Tae Jeong, or someone hiding in the background who may know more than they are letting on?
