Weak Hero Class 1 finally hit Netflix on March 25, 2025, more than two years after its original release on Wavve in South Korea. And now, it’s gearing up for a second part, with Weak Hero Class 2 set to premiere on April 25, 2025. Whether you’ve just finished bingeing or need a refresher, here’s a recap of what went down in Season 1, including that brutal ending, what really happened to So Ho, and what to expect from the forthcoming part.

Meet Si Eun, the Weak Hero

Si Eun, the Weak Hero

Yeon Si Eun is a model student teachers love — he’s at the top of the class and focused on his studies. He uses earbuds so that nobody disturbs him. Yes, he’s that quiet and focused. But being the smart, introverted kid at an all-boys school came with its challenges for Si Eun. Despite his efforts to steer clear of distractions, Yeong Bin, a full-time school bully and part-time student, gets agitated by his no-nonsense attitude. After facing an intense rebuttal following his first attempt to attack Si Eun, Yeong Bin uses a transfer student, Oh Beom Seok, to get to him.

Though Beom Seok comes from an influential background, he is weak-willed, thanks to his messed-up equation with his politician father, who adopted him for his public image. Having been bullied in his previous school, he succumbs to pressure and ends up hurting Si Eun.

But Si Eun doesn’t break down—he gets even stronger. He knew Beom Seok was tasked by Yeong Bin to hurt him. He puts up a strong fight against him and ends up breaking his nose, forcing Yeong Bin to transfer to save his face.

However, the revenge-hungry Yeong Bin doesn’t stop there. He pays professionals— the ones who have links to the underworld—to take him down. After knowing this, Beom Seok regrets his actions and pays Ahn Su Ho, their classmate who is trained in martial arts, sleeps in class, and does multiple part-time jobs to make a living, to protect Si Eun.

Si Eun and his unexpected trio

Si Eun, who has absent parents, never really formed any friendships in school. But seeing Beom Seok and So Ho side with him, his heart instantly melts, and the trio ends up building an unexpected friendship.

For a while, it seems like the three of them have each other’s backs. They take on the school’s worst bullies together, and for once, Si Eun feels like he’s not alone. The trio also becomes good friends with Yeongi, who was initially a part of the team that Yeong Bin hired to attack Si Eun.

But that trio doesn’t last

Here’s where it starts to fall apart: Beom Seok is struggling. He’s dealing with trauma at home, and he starts feeling left out. Su Ho, who has a casual way of speaking, looks down on him. As Si Eun and Su Ho grow closer, he thinks they don’t really see him as an equal — and instead of saying anything, he lets it build. And boil. And turn into resentment.

Then he flips. He teams up with the same bullies who made his life hell and sets So Ho up to get attacked.

What happened to Su Ho?

On So Ho’s birthday, Beom Seok decides to set up Su Ho. On the pretext of giving So Ho a birthday gift, he lures Yeongi and kidnaps her. He then sends So Ho a picture of Yeongi, asking him to come to the chamber where he has set up a foolproof plan to take him down. However, instead of So Ho, Si Eun ends up seeing the texts and gets beaten by the bullies.

When So Ho figures out what happened, he decides to face the attackers alone. By the time Si Eun realises what’s happening and gets back, So Ho is barely conscious. He’s covered in blood, his body’s wrecked, and it’s clear the damage is serious.

Later in the episode, we find out that So Ho is in a coma. The doctors say he’s in a vegetative state. No response. No recovery. Si Eun loses the one person who ever…

After So Ho’s attack, Si Eun breaks. The kid who used to fight smartly starts fighting angrily. He tracks down the people involved and beats them down with everything he has.

He then visits Su Ho in the hospital, and we see Su Ho waking up from a coma to talk to him. However, it’s most likely that it was all a fragment of Si Eun’s imagination, as Su Ho’s chances of survival are really low.

Did Beom Seok leave the country?

As for Beom Seok? Tired of his antics, his rich father pulls strings and sends him abroad before the police can even question him. In episode 8, we see Beom Seok at the airport, but whether he took the flight or not is the question Season 1 did not answer.

Why did Si Eun transfer schools?

After Si Eun attacked the bullies, he is on the verge of facing serious charges that could end him up at the juvenile detention centre. However, he is presented with a condition: he could transfer to the school. But due to Beom Seok’s father’s influence, he does not get admission into any school in Seoul despite his excellent grades.

Weak Hero Class 2 first look

He ends up at Eunjang High — a place known for being rougher, meaner, and more dangerous than the school he just escaped. The final shot shows him surrounded by new bullies, staring them down with a look that says, “Try me.”

What to expect from Weak Hero Class 2?

Season 2 picks up at Eunjang, with Si Eun walking into another battlefield — this time without his closest ally, Su Ho. He’s still smart, still sharp, but colder than ever.

The new season is expected to dive deeper into how Si Eun copes with that loss and how he survives in a school that might be even worse than the one he left behind. And maybe, just maybe, we’ll see him find a new reason to keep going.
