Weak hero Class 2- Episodes 5-6

Guilt, Goodbye Plans, and a Union Deal with the Devil

Episode 5 of Weak Hero Class 2 hits a more emotional tone — but don’t worry, the gut punches are still as powerful as the actual punches. This week dives into guilt, brotherhood, and one very painful decision.

We open with a flashback to that one quiet day of peace — Si-eun and Hu-min volunteering together, getting to know each other past the blood and bruises. Hu-min drops a bomb: Hyun-tak used to be a taekwondo champ, until he got injured because of Hu-min. It ended his sports career, and Hu-min’s never stopped blaming himself.

Si-eun gets it. He feels the same way about Su-ho. Guilt is the glue binding these broken boys together.

Cut to the present: Si-eun wakes up at Hu-min’s place. After that rooftop brawl, Hu-min carried his unconscious body home, patched him up, and stayed by his side. He promises it’ll never happen again. But Si-eun’s not buying the “fighting solves everything” narrative. He warns Hu-min: this cycle of violence only ends with someone in the ground.

So, Hu-min makes a surprising decision — he’ll end the grudge with Baek-jin by admitting defeat.

Plot twist: Baek-jin and Hu-min were childhood friends. Hu-min used to protect Baek-jin from bullies. Now Baek-jin’s the one running the gang and calling the shots — and he doesn’t like Hu-min anywhere near his turf.

We see just how cold Baek-jin really is when he picks up Seong-je from the hospital — not out of concern, but to interrogate him about what he told the cops. Seong-je, for once, is shaken. He tells Baek-jin everything and then says he’s taking a break. The cracks in the Union are starting to show.

Back at school, Si-eun, Hu-min, Jun-tae, and Hyun-tak are finally living like real friends — basketball, group study, actual laughter. For once, it feels like high school again. But of course, that doesn’t last.

Hu-min gets a call from the police: the boys who framed his dad for selling alcohol to minors just changed their story.Now they’re claiming Hu-min’s dad beat up one of them. When Hu-min arrives at the station, he sees those same boys laughing. That’s when Baek-jin texts.

“If you want this to stop, join the Union.”

Meanwhile, Si-eun walks into another kind of emotional ambush — his mom. She’s found out about the fights, the skipped cram school, the bruises. She hands him an acceptance letter for a school abroad and begs him to leave Korea before it’s too late. Si-eun lashes out, telling her she’s always left him behind. She breaks down, blaming herself for what happened to him and Su-ho.

It hits Si-eun hard. Maybe leaving is the right choice.

Back to Hu-min, who’s now cornered. Baek-jin is using everything against him — his dad, his friends. Hu-min stops going to school and finally gives in. He agrees to join the Union.

His first task? Get Seokham High’s leader, Gorilla, to fall in line. Hu-min tracks him to a nightclub and drops him with one punch. Seokham’s in.

The next night, Hyun-tak and Jun-tae find Si-eun’s home address and show up unannounced. Si-eun’s flying out the next day, but they just want one last hangout — one more basketball game under the fading sun.

Si-eun finally asks about Hu-min. They say he hasn’t been around. Concerned, Si-eun gives him a call. Hu-min, now fully swallowed by the Union, tells him not to worry: “Nothing will happen to you.” Then he hangs up.

The episode closes at the airport. Si-eun is at his gate, passport in hand. That’s when Jun-tae calls. And what he says is exactly what Si-eun’s been needing to hear for so long:

“What happened to Su-ho, Hyun-tak, and even Hu-min — none of that is your fault.”

And just like that, Si-eun turns around.

He’s not running away.

Motorcycles, Manipulation, and a Mid-Street Cliffhanger

Episode 6 of Weak Hero Class 2 takes everything we've built up so far — loyalty, guilt, friendship, corruption — and flips the table. It’s the most plot-heavy episode yet, but still delivers the raw emotion and brutal tension we’ve come to expect. Buckle up, because this one moves fast.

We start with Si-eun rallying the troops. He’s not leaving Hu-min behind. He knows Hu-min only joined the Union out of guilt — guilt for dragging his friends into danger. Si-eun, Hyun-tak, and Jun-tae are determined to bring him back.

Meanwhile, Hu-min is neck-deep in Baek-jin’s world, forcing yet another school to join the Union. Baek-jin throws him some dirty cash as a thank-you, and Hu-min takes it — not out of greed, but because his father needs money for legal fees. Flashbacks show us how Baek-jin became what he is: twisted by power, after Hu-min once taught him how to fight to defend himself.

In a gut-punch of a scene, Si-eun and the boys visit Hu-min’s home, only to get chewed out by Hu-min’s dad. He calls his son worthless — just like Hu-min’s mother. But Si-eun doesn’t stay quiet. He defends Hu-min, telling his dad flat-out: if you see no worth in someone like Hu-min, then the problem is you. Boom. Hu-min’s dad kicks them out, of course.

Still hunting for answers, they turn to Hyo-man, who finally spills some tea. Turns out Baek-jin and the Union are just middle-men. The real boss? CEO Choi — the kingpin behind the bowling alley and a shady motorcycle business under Daesung Construction. The entire Union operation is a slick front for money laundering and black market bike flipping. Stolen bikes are repainted, registered with new plates, and sold again — and again. The kicker? CEO Choi keeps a register of every kid involved, ensuring total control.

Si-eun plans to confront Baek-jin head-on and tells Hyun-tak and Jun-tae to stay put. (Of course, they don’t.) While Si-eun waits at the bowling alley, the other two sneak into Daesung Construction — because what could go wrong?

Eventually, Baek-jin arrives. Si-eun hits him with a psychoanalysis so on point it makes Baek-jin pause. Si-eun says Baek-jin’s obsession with Hu-min isn’t about power — it’s fear. Hu-min knows the real Baek-jin. That scares him. Si-eun calls it what it is: Baek-jin wants to control the only person who ever saw him as a friend. And he can’t stand that he’s lost that person.

But Baek-jin shakes it off and shows Si-eun the CCTV feed — Hyun-tak and Jun-tae have broken into the Union’s secret documents room. He’s already sent guys after them. Si-eun snaps, grabs whatever he can as a weapon, and nearly goes full berserker… but he’s outmatched.

Enter Hu-min.

He pulls Si-eun out and tells him to leave. He’ll handle it.

Earlier that day, Hu-min had already told Baek-jin he’s out. No more jobs, no more loyalty. “You can destroy everything around me, but we will never be what we were.” When Baek-jin tries to lash out, Hu-min easily dodges — and delivers a clean punch to his face before walking away.

Meanwhile, Hyun-tak and Jun-tae find the ledger of stolen bikes at Daesung Construction — the proof they need. But just as they’re leaving, the Union gang ambushes them. Hyun-tak goes full fighter mode, even holding his own against Dong-ha and Seong-mok. Jun-tae — yes, Jun-tae — steps up too. They fight their way out and go on the run, Union boys hot on their heels.

Just when you think the episode’s wrapping up, bam — we get hit with a cliffhanger.

Si-eun gets a call from the hospital. Su-ho’s condition has worsened. The nurses can’t reach his guardian. Si-eun, shattered and distracted, crosses the road without looking — and the screen cuts as a speeding truck barrels toward him.

DramaZen's Opinion

Okay, Weak Hero Class 2 is officially messing with my emotions — and I love it. Episodes 5 and 6 are a rollercoaster of loyalty, trauma, betrayal, and underground crime rings (because of course there’s a secret motorcycle gang now). These episodes gave us everything: raw emotional moments, shocking reveals, and one of the most stressful cliffhangers of the season.

Episode 5: "Don’t Call It a Comeback, Because I’m Still Hurting"

We start slow — Si-eun wakes up at Hu-min’s house after that rooftop beatdown, bandaged up and barely breathing. Hu-min promises to never let it happen again. Cue the heartbreak.

Then we get that beautiful flashback to volunteer day, where Hu-min opens up about how he ruined Hyun-tak’s taekwondo career. He’s been carrying that guilt for years, just like Si-eun carries what happened to Su-ho. Trauma bros. Broken boys bonding. My chest hurt.

Things seem calm — until Baek-jin starts blackmailing Hu-min into joining the Union. And it works.

Next thing you know, Hu-min’s out there punching school leaders and bringing in new recruits. It’s not because he’s power-hungry — it’s because he’s protecting his dad, who’s being set up by the Union's dirty games. And Hu-min’s dad? Absolutely awful. When Si-eun defends Hu-min and tells his dad, “If you think he’s worthless, you’re the problem,” I clapped. Out loud.

The ending of Episode 5 is devastating. Si-eun’s mom tries to send him abroad to escape all of this mess. Si-eun almost leaves. ALMOST. But then Jun-tae calls him at the airport and says the words that broke me:
“What happened to them isn’t your fault.”
Cue Si-eun turning around. Hero mode: reactivated.

Episode 6: "Welcome to the Union — Please Steal a Motorcycle"

Things go from bad to criminal empire real fast.

We find out the Union is working under a man named CEO Choi, who owns the bowling alley, a sketchy motorcycle company, and everyone's soul. Baek-jin is running a whole motorcycle theft + laundering ring using high school boys. I’m talking stolen bikes, repainted frames, fake plates, black market sales — this ain’t petty crime anymore. This is Fast & Furious: High School Edition.

And Hu-min? He’s stuck in the middle. He’s doing dirty work to keep his dad out of jail and his friends out of danger. But he’s clearly dying inside.

Si-eun, Hyun-tak, and Jun-tae try to get through to him — but Hu-min’s too deep. Si-eun even confronts Baek-jin and gives him a full therapy session about fear, control, and childhood abandonment. It’s brilliant. Baek-jin almost flinches. Almost.

But then we find out Hyun-tak and Jun-tae didn’t listen to Si-eun (of course) and broke into the Union’s headquarters looking for dirt. They find it — a ledger full of stolen motorcycle records — but also find a beatdown waiting for them.

Meanwhile, Hu-min tells Baek-jin he’s done.
“We’ll never be friends again.”
And punches him right in the face.
I screamed.

The ending? STRESS LEVEL 100.

Si-eun gets a call from the hospital. Su-ho’s condition just got worse. Si-eun, frozen, steps into the road… and the screen cuts to a speeding truck.

Y’ALL.

Final Thoughts:

Episodes 5 and 6 are peak Weak Hero. The bromance? Complicated. The villains? Messier than ever. The stakes? Higher than they've ever been.

Hu-min is breaking under the pressure. Si-eun is breaking under the guilt. And Baek-jin is straight-up unhinged. Jun-tae and Hyun-tak deserve best friend awards for life. And Seong-je? Still terrifying.

Also, can we please protect Si-eun? At this point, he needs a therapist, a vacation, and a forcefield.

I’m terrified for Episode 7.

Will Si-eun survive the truck? Will Hu-min take down the Union from the inside? Will Jun-tae finally get a break?

Tune in next week — and bring tissues.
