Identity MysteryForbidden RomanceJoseon DynastyPolitical IntrigueNovel Adaptation
Twelve years after eight-year-old Sim Hongrang vanished from one of Joseon’s most powerful merchant families, a grown man claiming to be him walks back through the front gate — passing every test his relatives throw at him, remembering nothing of the childhood he supposedly lived. His older step-sister Sim Jae-yi has spent those twelve years refusing to stop looking for her real brother, and his convenient blank memory is the first thing that makes her doubt he’s the boy she lost.
Dear Hongrang complicates that doubt fast: the closer Jae-yi gets to proving him a fraud, the more she finds herself drawn to him anyway, and the family secrets she uncovers along the way turn out to implicate almost everyone she trusts. Over eleven episodes, the show plays out as a locked-room identity mystery wrapped around a romance the two leads keep telling themselves is off-limits, tangled up in a merchant-guild power struggle and a possible killer hiding in the family’s inner circle.

Spoiler-light recaps — enough to remember where you left off, nothing that ruins the ride.
EP 01
Rainbow Hong, Shining Rang – My Brother Hongrang
May 16, 2025
Twelve years after eight-year-old Sim Hongrang vanished, a grown man claiming to be him returns to the merchant family that never stopped waiting — and passes every identity test they throw at him. His older step-sister Sim Jae-yi doesn’t buy it: a man with zero memory of his own childhood is either grieving something worse than she knows, or lying to her family’s face. The premiere doesn’t resolve that question — it just makes clear Jae-yi is the only person in the house willing to keep asking it.
EP 02
The One Who Stole Our World
May 16, 2025
Jae-yi and Hongrang chase the same rumor from opposite directions — a ghost supposedly abducting children, tied to a shadowy figure called the Snow Man and a painter nobody can name. Jae-yi’s version of that investigation nearly gets her killed by a bounty hunter, and Hongrang’s rescue does more to convince her he’s genuine than any birth record could. The episode’s real gut-punch comes after: Hongrang telling her, unprompted, that she’s his sister — a claim that should settle her doubts and somehow only deepens them.
EP 03
The Most Authentic Replica
May 16, 2025
Hongrang’s rescue buys him goodwill he hasn’t earned with everyone — Sim Mu-jin isn’t convinced, and he’s building a case to expose Hongrang as a fraud in front of the whole family at his own birthday celebration. Jae-yi, meanwhile, starts losing the argument with herself: the emotional walls she’s kept up against Hongrang start cracking exactly when she can least afford them to. The episode sets a trap and a courtship on the same collision course, due to detonate at a party everyone’s pretending is a celebration.
EP 04
Our Reflective Scars
May 16, 2025
Min Yeon-ui calls a guild-wide meeting to consolidate power while her husband Sim Yeol-guk quietly plots a countermove — the marriage at the center of this family is really two rival operators sharing a house. Hongrang gets caught in the crossfire with the worst assignment yet: an order to make sure Jae-yi doesn’t survive long enough to expose him. What plays as a political power struggle on the surface is really about how far a man will bend his conscience to keep a lie he never asked to tell.
EP 05
The Thicker the Veil, the Clearer the Heart
May 16, 2025
Jae-yi’s doubts keep eroding into something closer to affection as she pieces together Hongrang’s past, right as Lady Min tries to marry her off — a match that reeks of leverage more than love. Hongrang and Mu-jin, adversaries in everything else, land on the same suspicion about what Lady Min is really doing. Hongrang’s answer is to intervene directly, pulling Jae-yi out of the wedding as a black-clad rescuer, and the moment does more for their relationship than any of the family’s engineered scheming.
EP 06
Nothing Mu, Finished Jin – Brother Mu-jin
May 16, 2025
The plan to stop Jae-yi’s marriage collapses, and she’s left with none of the agency she thought she’d bought back — a hard reset on how much control she actually has in this family. Yeol-guk and Yeon-ui’s rivalry stops simmering and starts boiling, less a marriage than a cold war with children caught in the blast radius. It’s the bleakest episode yet about what family actually costs the people inside it.
EP 07
Roaring Waves
May 16, 2025
With Mu-jin’s life on the line, Jae-yi does whatever it takes to save him — no hesitation, no negotiating with herself first. A strange rumor arrives at the worst possible time: a child who should be dead is reportedly walking around again, and it rattles Hongrang more than anything else has this season. The show finally lets its identity mystery bleed into something closer to the supernatural, or at least close enough that Hongrang can’t dismiss it.
EP 08
Imperfect Jae, Departing Yi – My Name is Jae-yi
May 16, 2025
Jae-yi makes the call nobody saw coming — she leaves with Mu-jin, choosing his safety over whatever she and Hongrang were building. Yeol-guk, meanwhile, discovers a conspiracy against him and moves into full damage control, protecting the family name at any cost. It’s the first time Jae-yi gets to define her own choice instead of reacting to everyone else’s — and it costs her the person she just started letting herself trust.
EP 09
The Living Offering
May 16, 2025
A manhunt for Hongrang and Jae-yi forces them into hiding together, and there’s nothing left to perform once survival is the only thing on the table. Whatever tension they’d been dancing around dissolves fast when the two of them are relying on each other to make it through the night. It’s the show’s most stripped-down episode — no guild politics, no family theater, just two people finally being honest.
EP 10
A Bittersweet Farewell
May 16, 2025
Hongrang’s capture hands Yeol-guk a chance to rebuild his authority using Hongrang’s name as leverage, but the real threat has already moved past him — Grand Prince Hanpyeong sets his endgame in motion with the kind of ruthlessness that makes every earlier scheme look small. The power players spend this episode fighting the wrong war while Hanpyeong quietly wins the real one.
EP 11
Forever and After
May 16, 2025
The truth about who Hongrang really is finally comes out, along with the tragic fate of the boy who vanished twelve years ago. Every major player gets their reckoning — Yeon-ui’s manipulations catch up with her, Yeol-guk’s grip on the guild breaks, and Hanpyeong’s grand scheme collapses along with him. Jae-yi ends up somewhere she never expected: not avenged, not fully healed, but finally free to build something of her own out of everything she survived.
🏁 Ending Explained
Full spoilers ahead — everything that happens in the finale and what it all means.
⚠️ Spoiler Warning — This section covers the full finale of Dear Hongrang. Stop here if you haven’t finished the series.
What actually happened The man who came back isn’t the original Sim Hongrang — the real Hongrang died as a child, and the man Jae-yi fell for spent twelve years living under a name and a face that were never his to claim. The finale finally answers the question the entire series is built on: not “is he lying,” but “what happened to make a stranger take a dead boy’s place,” and the answer runs straight through Min Yeon-ui’s obsession and a painter’s cruelty that started this whole tragedy.
Where the schemers land Min Yeon-ui’s madness finally catches up with her — everything she orchestrated to control the guild and her son’s fate collapses under its own weight, and her ending is less punishment than inevitability. Grand Prince Hanpyeong, the real architect behind the missing-children plot, sees his grand ambitions fail along with him, and his co-conspirator the Painter — the man responsible for years of cruelty hidden behind art — meets a definitive end of his own.
What happens to Jae-yi and Hongrang The reveal that Hongrang was never Jae-yi’s blood brother is what finally clears the emotional minefield the show spent eleven episodes tiptoeing through — the two of them were never wrong to fall for each other, they just spent most of the season believing they were. It doesn’t erase what they went through to get there, and Dear Hongrang doesn’t pretend it does; their ending reads as earned rather than easy.
The family that’s left standing Sim Yeol-guk’s hold on the merchant guild doesn’t survive the fallout — his authority, built on decades of the same manipulation Yeon-ui practiced, is irrevocably broken by the end. Sim Mu-jin comes out the other side of his own arc with something closer to freedom, finally released from the weight of being the Sim family’s disappointing alternative to a son who was never real.
The KDW verdict Jae-yi doesn’t get a clean happy ending, and that’s the right call — she gets purpose instead, dedicating herself to the abducted children the story spent its runtime failing, which is a better use of a resilient female lead than a wedding would’ve been. Dear Hongrang closes as a mystery that solved itself honestly and a romance that earned the right to exist once the lie underneath it stopped mattering.
✍️ KDramaWorlds Editor’s Take
Worth the watch? Our honest answer, and who it’s aimed at.
🎭 Stolen Identity 💔 Forbidden Almost-Siblings 🗡️ Merchant Guild Politics 🖤 Joseon Gothic Mystery
Lee Jae-wook playing a man who might not know his own name is the kind of role that could tip into gimmick, but Dear Hongrang plays it straighter than that — his Hongrang carries real uncertainty about who he is underneath the performance of confidence he has to give everyone else. It’s a different flavor of identity mystery than Missing Crown Prince, less comedic mistaken-identity chaos and more slow psychological unraveling of a man who has to solve his own backstory before anyone else does.
The sibling framing is the show’s boldest swing — it spends most of its runtime letting Jae-yi and Hongrang’s chemistry build under the assumption that acting on it would be transgressive, which makes every charged scene between them do double duty as romance and moral tension at once. That kind of bittersweet, obsession-adjacent melodrama shares DNA with Captivating the King, another Joseon-set drama willing to let love and power corrode each other in real time.
Eleven episodes is a tight runway for a mystery this layered — missing children, a shadow painter, a guild succession war, and a decade-old cover-up all competing for the same screen time — and the back half occasionally shows the seams of everything it’s trying to resolve at once. What holds it together is that the emotional stakes never stop being personal, even when the plot mechanics get busy.
👍👍👍 BEST FOR 👍👍👍
🎭 Fans of slow-burn identity mysteries where nobody, including the lead, is sure who he is 💔 Anyone who wants their forbidden romance dressed up as a family melodrama 🗡️ Viewers who like their historical dramas with real political stakes, not just costume drama
⚖️ Final Verdict
What works
•Lee Jae-wook and Jo Bo-ah sell a relationship built entirely on tension neither of them can act on
•The eventual identity reveal recontextualizes nearly every earlier scene without feeling like a cheat
•A brisk 11-episode Netflix run that doesn’t overstay its central mystery
What to know first
•The final stretch juggles multiple villain payoffs at once, which compresses some resolutions
•This is a slow burn — the romance takes most of the season to become text instead of subtext
•Best watched knowing upfront that the ‘siblings’ framing gets resolved by the finale, not left hanging
8.1 / 10— A Joseon-set identity mystery that earns its forbidden-romance tension by actually answering the question it spends eleven episodes asking.
