tvN’s “My Bias, My Boss” is entering turbulent territory as a new cast member reshapes the central romantic narrative. The webtoon-based drama follows Nam Da Reum, an ambitious professional who accepts employment at Appello specifically to encounter her longtime idol, Lee Chan. However, her plans transform when she finds herself drawn to Kang Ha Gi, the company’s CEO. The pair have recently begun dating, a development that now faces a serious threat.
The Strategic Partnership and Its Hidden Cost
Kang Ha Gi had initiated collaboration talks with HAN, the globally recognized fashion brand, as part of his defensive strategy against SE Trading. The rival firm has repeatedly targeted Appello’s intellectual property and commercial ventures, and the HAN partnership represented a significant counteroffensive. He assembled a dedicated team and committed substantial resources to secure this collaboration. The arrangement appeared straightforward until Han Jeong Yeon surfaced as HAN’s representative, introducing a complication no one had anticipated when negotiations began.

A Shared Past Complicates Everything
The First Love Factor
The dramatic irony cuts deeper because Han Jeong Yeon holds sentimental significance for both men currently involved in Nam Da Reum’s romantic orbit. She represents the first love of both Kang Ha Gi and Lee Chan, a connection that transcends the current romantic dynamic and introduces layers of emotional complexity that Nam Da Reum must now navigate. Nam Da Reum had no knowledge of this shared history when she began her relationship with Kang Ha Gi, making Han Jeong Yeon’s emergence a shock to the equilibrium she had carefully constructed.
Lee Chan’s Hidden Agenda
Complicating matters further, Lee Chan had previously requested that Han Jeong Yeon deliberately unsettle Kang Ha Gi, transforming her professional obligations into an opportunity for personal interference. The proximity required by their business collaboration now serves Lee Chan’s hidden agenda. As the CEO of HAN, Han Jeong Yeon inevitably spends increasing amounts of time with Kang Ha Gi, a situation that transforms from straightforward professional interaction into the exact romantic threat Nam Da Reum had begun to fear.
The Emotional Toll Visible in New Stills
Nam Da Reum’s Visible Distress
The production released promotional stills that offer glimpses into the escalating emotional atmosphere surrounding the three characters. Nam Da Reum’s demeanor shifts noticeably, her usual professional composure replaced by visible anxiety and distress. Even when physically held by Kang Ha Gi, her face betrays internal conflict rather than the contentment one would expect from a newly confirmed couple. The imagery suggests that something significant has already transpired between the three parties, though the precise nature of that conflict remains unrevealed by the preview materials.
Han Jeong Yeon’s Inscrutable Gaze
In a separate still, Han Jeong Yeon directs an unreadable gaze toward Nam Da Reum, the kind of expression that carries unstated meaning and unresolved tension. The composition raises urgent questions about what Nam Da Reum perceives as she observes her romantic partner in the presence of his former first love. The situation positions Han Jeong Yeon’s entrance into the narrative as a destabilizing force with potentially far-reaching consequences.
Broadcast Schedule and Where to Watch
“My Bias, My Boss” episode 10 will premiere on September 1 at 8:45 p.m. KST on tvN. Viewers outside South Korea can access both current and previously aired episodes through Viki, the streaming platform distributing the series internationally. The promotional stills released in advance of this episode strongly suggest that the love triangle dynamic will dominate the narrative, with the three characters navigating the emotional and professional fallout of Han Jeong Yeon’s emergence as both a business force and personal complication.
Unresolved Questions and Future Conflict
The introduction of Han Jeong Yeon represents far more than a simple romantic obstacle to overcome. Her position as HAN’s representative gives her legitimate and ongoing reasons to remain in Kang Ha Gi’s professional orbit, making her presence impossible to dismiss or minimize. Nam Da Reum now faces the difficult challenge of processing her boyfriend’s romantic history while simultaneously managing the natural insecurity that accompanies the knowledge that her romantic rival once held his heart. Kang Ha Gi, meanwhile, must navigate conflicting loyalties between the business partnership that could significantly strengthen Appello’s competitive position against SE Trading and the romantic commitment he has recently made to Nam Da Reum.
The fundamental question of Han Jeong Yeon’s true intentions—whether they are purely professional, partially influenced by Lee Chan’s prior request, or driven by her own unresolved feelings toward Kang Ha Gi—remains entirely open. Her emotional inscrutability in the released still suggests that the drama will not reveal her underlying motivations immediately, instead allowing tension to accumulate steadily as the three characters navigate their complex relationships through the episodes ahead.
