Why did D.N.X disband in My Bias, My Boss? The show kept the reason back until episode 10 of 12
My Bias, My Boss sold itself as fluff: a fangirl gets a job at her idol's fashion startup, accidentally falls for the grumpy CEO instead, hijinks. The tvN rom-com, which wrapped its 12-episode run on September 8, delivered all of that on schedule.
But the show was quietly running a second engine underneath the office flirting — the question of why D.N.X, the fictional boy group that heroine Nam Da-reum built twelve years of her life around, disbanded a decade ago. And it made us wait until episode 10 of 12 for the answer.
The reveal
The reason D.N.X fell apart wasn't a contract dispute or creative differences or any of the usual press-release language. Photos of member Roy with his boyfriend were leaked. In an industry where idols dating anyone is treated as a scandal, Roy being outed detonated the group entirely: he was pushed out, the fallout swallowed everyone, and D.N.X quietly ceased to exist.
The gut-punch layer, as Dramabeans' recap of episodes 9-10 lays out, is what happened after: Roy has spent the years since living in hiding, blaming himself for the disbandment — as if being outed were something he did to his members rather than something done to him. The scene where superfan Seul-ah finally finds her bias and tells him she was never once ashamed of him is the best idol-fan moment the drama produced, full stop.
Why the twist works
- It reframes the entire series. Lee Chan's weird melancholy, the members scattering into acting and obscurity — all of it suddenly reads differently.
- It's uncomfortably plausible. K-pop has ended careers over far less than what happened to Roy, and the show knows its audience knows that.
- It earns the finale. A D.N.X reunion was on nobody's bingo card in week one; by the last episode it was the thing viewers wanted most, and the show delivered it — with Roy on stage and Da-reum's star emblem stitched into the reunion concert outfits.

The show knew what it had
None of this lands without a cast that treats a rom-com like it matters. The drama opens with Da-reum's narration — "It was his song that rescued me from my loneliness" — and then spends twelve episodes taking that sentence completely seriously.
The leads clearly took each other seriously too. Kang Hoon, who plays CEO Kang Ha-gi, said of his co-star:
"Kim Hye Jun gave me a lot of cheerful energy."
Which, honestly, tracks — the show radiates it. It just also turned out to have one of the saddest backstories of the year hiding in the B-plot, and had the discipline to sit on it for ten episodes. Respect.
