Just when I thought Mercy for None couldn’t get any darker or more intense, Mercy for None Episode 5 and 6 hit like a thunderstorm. These two episodes dive deep into betrayal, shifting power plays, and hidden truths, setting the stage for what feels like an all-out war. The pacing might slow down sometimes, but the stakes have never been higher — and that final twist? Jaw-dropping. Mercy for None Episode 6

Mercy for None Episode 5 Recap
We begin Episode 5 with a chilling flashback to Gi-seok’s death- not by some gang punk, but by a deadly masked assassin. Gi-seok puts up a fight, but it’s a losing battle, and the blade to the neck seals his fate. Meanwhile, Detective Han, who’s been sitting outside all along, walks in too late and files the case as a homicide.

Fast forward to the present, Gi-jun is pulled out of the water- alive, but barely. Thankfully, Hae-beom finds him in time and gets him help. Elsewhere, the two titans- Chairman Ju-woon and Chairman Bong-san — come face to face. Bong-san openly admits he tried to have Gi-jun killed to protect his son and throws serious accusations at Ju-woon’s way. He even brings receipts, pointing out how Detective Han is linked to Juwoon Group through JW Gallery. The confrontation ends with an ominous ultimatum: only one of them can survive.

Things escalate quickly. Bong-san’s men get arrested, Ju-woon gains the upper hand, and the long-expected gang war ends too easily. Bong-san is defeated and, shockingly, killed by Ju-woon himself. But one man from Bong-san’s crew is left standing — it turns out he’s Yeong-do’s mole.
And here’s the mic-drop moment: in Yeong-do’s room, we see a list of crossed-out names- Bong-san, Jun-mo, Gi-seok. Only one name remains: Ju-woon.
Mercy for None Episode 6 Recap
Episode 6 wastes no time. Yeong-do encourages Geum-son to strike against his father while the chaos from Bong-san’s fall is still fresh. Later, Gi-jun tries to take down Yeong-do, but An Tae-hwan — the former enforcer we last saw in prison — intervenes. Turns out he’s out and very much back in the game.

Mercy for None Episode 6 Review: Choo Young Woo
The family feud intensifies as Geum-son tells Ju-woon he’s taking over the board meeting. Despite his father’s protests, he’s working with Yeong-do now. And he’s not afraid to shoe muscle — when a board member walks out, he’s attacked, forcing the others to fall in line. Ju-Woon, sensing his end is near, opens his safe and pulls out a gun.
Meanwhile, Gi-jun confronts Tae-hwan in a grim showdown. Tae-hwan, bitter over the past and now with a prosthetic hand, admits defeat — but ends things on his terms by pushing the knife into himself. It’s a painful, emotional scene, though it would’ve hit harder with more backstory on their bond.
Back at Ju-woon’s home, the inevitable happens — Yeong-do shows up and kills him after a brutal fight. When Gi-jun walks in, he finds Ju-woon’s lifeless body…and gets arrested on the spot. Geum-son, who had bugged his father’s room, hears the whole murder play out live.

But Yeong-do’s plans start to unravel. During Gi-jun’s prison transport, he fights back, escapes, and is rescued by Seong-won, who defies Yeong-do’s orders. Seong-won gives him a burner phone and a key item — Ju-woon’s pipe- and sends him on his way.
In the meantime, Geum-son isn’t playing nice, either. He uses his position as a prosecutor to raid Yeong-do’s office and expose him as Ju-woon’s killer. To tie off loose ends, Geum-son brings in Kaneyama — the same assassin who killed Gi-seok — and orders him to kill Gi-jun. But wait—— Yeong-do isn’t dumb. In a flashback, we learn he secretly recorded Geum-son’s master plan months ago and hid the recording in a package at his golf club. That final scene? Chef’s kiss.
Mercy for None Review
There’s no denying Mercy for None delivers on suspense and style. The fight choreography, especially in the Gi-seok and Gi-jun sequences, is top-notch. The moody visuals —- shadowy parking lots, cold confrontations —- create such a sleek, noir atmosphere.

Mercy for None Episodes Review:
But if I’m being honest, the emotional beats feel rushed. Bong-san’s death should have shaken the foundation, but it comes and goes without much weight. Ju-woon’s murder? Equally underwhelming, considering how central he was to the story. We needed more time to process these moments and truly feel their impact.
That said, Yeong-do is easily the most compelling character right now. The way he’s been operating in the shadows and slowly climbing the ladder? It’s both terrifying and fascinating. Geum-son is also stepping up as a more calculated and dangerous player, but his character still lacks emotional depth. I wish we got to see more of his internal struggle before he went full dark mode.
Final Thoughts
Mercy for None Episode 5 and 6 serve as a massive turning point. With Ju-woon and Bong-san gone, the real game begins. The power vacuum is wide open, and it’s clear that Yeong-do and Geum-son are both trying to fill it—— in very different ways. Gi-jun, as always, is caught in the middle and now with a target on his back.
These episodes weren’t perfect — a little more emotional build-up and character backstory would’ve gone a long way. But the plot twists, betrayals, and shifting loyalties are Pure K-drama gold. And now that all the cards are on the table, I can’t wait to see who makes the next move.
