Okay, K-drama bestie, we need to talk about something. So Ji Sub is back. And not just back, he’s back with blood in his eyes, a baseball bat in hand, and zero chill in the Mercy For None trailer. Netflix just dropped it, and if you haven’t watched it yet, what are you even doing?
Seriously, if you’ve ever cried over a revenge plot at 3 AM or screamed “GET HIM!!” at your screen, this upcoming Kdrama 2025 is calling your name.
So Ji Sub + Baseball Bat = We’re Watching That

The trailer starts off quiet. Too quiet. And then BAM, you see So Ji Sub as Gi Jun, walking through a dark alley like he owns the night. It’s moody. It’s broody. And yeah, he’s serving full-on revenge daddy energy.

Plot twist: his younger brother (played by Lee Jun Hyuk) is mysteriously murdered. So what does our ex-gangster king do? He picks up a weapon and walks straight back into the world he left behind.
It’s giving “you messed with the wrong family” vibes, and I am so here for it.
If you’ve binged all the So Ji Sub movies and TV shows like I have, you know this man doesn’t play when it comes to intense roles. But this time? He’s out for blood, and honestly… same, bro.
Visuals Darker Than My Life Choices

Let’s talk style, because this trailer? A whole vibe. Dark alleys, neon lights, flying fists, slow-mo punches, chef’s kiss. You can tell this isn’t your typical popcorn K-drama. It’s got that gritty, Taxi Driver meets The Glory meets “don’t breathe too loud or someone might get stabbed” kinda energy.
And the action scenes? Wild. There’s this one shot where So Ji Sub takes down like seven guys in a row and I swear, I clutched my chest like an ajumma in a weekend drama.
Also, tiny detail, but kind of major? He once cut his own Achilles tendon to leave the gang life. Who does that?! (Besides people in K-dramas who are clearly allergic to peace.)
The Poster Is Basically a Spoiler… and I Love It

Now the poster. OMG. So Ji Sub is standing in an alley, bodies everywhere, blood on the ground. It’s like he just came out of a boss fight in level 97 of “Vengeance: The Game.”
And the tagline? “The rules have been broken, and he is back.” Chills. Literal chills.
If you’re the type who picks dramas based on poster aesthetic (no judgment, I do too), this one just earned itself a permanent spot on your list of upcoming Kdrama 2025 obsessions.
You Know What to Do Next
Mark your calendar. Mercy For None drops on Netflix on June 6, 2025. If you’re into heart-pounding stories, dark aesthetics, or just So Ji Sub movies and TV shows in general, you do not want to miss this.
Go watch the trailer. Share it with your drama group chat. Prepare your snacks.
And get ready to scream at your screen, because this one’s gonna hurt in the best way.
