My Bias, My Boss Explained: tvN's New Idol Office Romance With ITZY's Yuna

tvN just dropped its new Monday-Tuesday drama tonight, and the internet has one question: is this the next Lovely Runner? My Bias, My Boss (최애의 사원) premiered August 3 at 8:45 PM KST, and it's already got two things going for it that Korean fans can't stop talking about — a love triangle built entirely on fandom culture, and ITZY's Yuna in the cast.

What Happened

My Bias, My Boss follows Nam Da-reum (Kim Hye-jun), a die-hard fan of idol group D.N.X who lands a job at Appelo, the fashion platform company her bias Lee Chan (Cha Woo-min) co-founded. She takes the job hoping to finally meet her favorite idol face to face. Instead, she gets tangled up with Appelo's prickly CEO, Kang Ha-gi (Kang Hoon), before she even runs into Chan. What starts as a dream job for a fan spirals into a full office love triangle.

The drama is based on a webtoon that racked up hundreds of millions of views, and it's written by Lee Young, who wrote tvN's Siren just five months ago in the same Monday-Tuesday slot. It runs 12 episodes and streams on TVING and Wavve domestically. International viewers get it on HBO Max, according to entertainment outlets covering August's K-drama slate.

The ITZY Connection

Here's the part that's catching K-pop fans off guard: ITZY's Shin Yuna joined the cast. She's not one of the three leads, but her presence alone is enough to pull K-pop stans who'd otherwise skip a straight office rom-com into watching episode one. It's the kind of casting that turns a drama premiere into a K-pop crossover event, and Korean entertainment coverage has been name-dropping her alongside Kang Hoon, Kim Hye-jun, and Cha Woo-min in nearly every casting article since the announcement.

Why Everyone Keeps Comparing It to Lovely Runner

Korean outlets aren't being subtle about this one. Lovely Runner — the 2024 time-slip idol romance that hit a 5.8% peak rating and became a genuine syndrome — is the reference point every single preview article reaches for. The comparison makes sense: both shows are built on the fantasy of an ordinary fan getting impossibly close to their idol. But My Bias, My Boss swaps the fantasy device for something a lot more mundane and, honestly, more relatable — just getting hired at the right company.

🇰🇷 THE KOREAN SIDE / 🌍 THE GLOBAL SIDE / 📊 THE GAP

🇰🇷 Korea: Coverage is obsessed with the ratings math — can this beat its lead-in show See You at Work Tomorrow!, which opened at 4.8% and held steady? Entertainment outlets are also leaning hard into the "성덕" (successful fan) angle: the fantasy of turning your fandom into your actual career. That's a very specific, very real cultural touchpoint in Korea's idol fan economy, and it's doing a lot of the marketing heavy lifting.

🌍 Global: English-language coverage frames it more simply, as an office rom-com with a love triangle and a K-pop-adjacent hook. Koreaboo and SCMP both slotted it into their "what to watch in August" roundups without digging into the "성덕" concept at all — it just reads as "fan gets hired at idol's company," which loses some of the specific cultural weight Korean fans are picking up on.

📊 The Gap: Korean audiences are watching this as a wish-fulfillment story about fandom itself. Global audiences are watching it as a love triangle rom-com that happens to have an idol in it. Same show, different lens.

Why It Matters

tvN is clearly chasing the Lovely Runner formula again, and the timing isn't random — idol-adjacent romance is one of the few K-drama subgenres that reliably crosses over into K-pop fan spaces, which means built-in cross-promotion between two massive, overlapping audiences. Throw in an actual ITZY member in the cast, and Appelo's office starts looking a lot like a test case for how far a network will go to blur the line between K-drama and K-pop marketing.

What Fans Are Saying

Korean drama forums lit up the moment casting news dropped back in July, with a lot of the chatter centered on the risk of putting a real idol inside a fictional idol storyline — some worried it would feel gimmicky, others thought it was exactly the kind of stunt casting that makes a premiere week unmissable. On the international side, fans on X were quick to point out how rare it still is for an active girl group member to take on a drama role mid-promotion, and a fair number of ITZY stans said they were tuning in purely for Yuna's scenes regardless of how the main triangle plays out.

There's also a smaller but louder thread of skepticism from viewers who felt burned by past "idol fan gets the idol" dramas that leaned too hard on fantasy and too light on actual character writing. Writer Lee Young's track record is doing some of the reassurance work here — her last project, Siren, aired in the same tvN Monday-Tuesday slot just five months ago, and industry watchers see the back-to-back scheduling as a vote of confidence from the network rather than a coincidence.

FAQ

Is My Bias, My Boss based on a true story?
No — it's adapted from a webtoon and is entirely fictional.

Is this connected to Lovely Runner?
Not officially. They're unrelated productions, but Korean media keeps comparing them because both center on a fan getting unusually close to an idol.

How big is Yuna's role?
She joined the cast alongside the three leads, though her exact role size hasn't been detailed in casting reports yet — we'll update once episode credits confirm it.

💬 Jamie's Take: I'll be honest, the second I saw "성덕" in a headline I knew exactly what kind of show this was going to be, and I mean that as a compliment. Korea has been quietly perfecting the fan-fantasy office romance for a couple of years now, and putting an actual idol in the cast instead of just writing about one is a smart move I'm surprised more networks haven't tried. Whether it clears the Lovely Runner bar is a different question — that show was lightning in a bottle — but as a Monday night watch with your camera off and your snacks out, this has exactly the setup to work.
