Strong Heroes

Summary:

At Byuksan High, strength ruled and silence meant survival. Yeon Si-Eun—quiet, brilliant, invisible by choice—seemed like the perfect victim. But when pushed, he fought with the same precision he studied: no wasted moves, no mercy.

Beside him stood two unexpected allies: Ahn Suho, the loud, loyal brawler with a crooked grin and a bleeding heart; and Oh Beom-Seok, the anxious rich kid desperate to matter. Together, they formed a fragile trio, held together by trust and the bruises they earned.

Then came Choi Shea.

Observant, calm, and as stubborn as Si-Eun was cold, Shea was the only one who saw through his quiet armor. She never asked to be part of the chaos, but her presence was a quiet storm—steady, impossible to ignore. And in the blur of battles, she moved a heart he thought he’d buried.

Their bond changed everything.

But in a world like theirs, nothing that real ever stays untouched.

Notes:

A Little Note from Your Newbie Author

I wrote this after dreaming of Park Jihoon as Yeon Si-eun—months after Weak Hero Season 2 was released. That dream sparked something in me, reigniting a love for storytelling that I hadn’t felt in years. I don’t think I’ve written anything seriously since my GOT7 fangirl era!

None of my past works ever saw the light of day, so sharing this now makes me both nervous and excited. Please be kind—this is simply my personal interpretation of what it might be like to exist in the world of Weak Hero. You’ll notice a lot of similarities to the original series. At first, I aimed to stay loyal to the canon story, but as I kept writing, I naturally leaned into my own creative vision. That said, I still deeply love the original TV series, and I mean no offense to manhwa fans—this is just my fantasy take.

I’m not sure how often I’ll be posting yet, but the full outline for Season 1 is already done! I’ll be polishing it chapter by chapter and am currently working on my version of Season 2. Still figuring out exactly where the story will go, but for now…

Please enjoy the prologue and Chapter 1.

Chapter 1: Prologue First Year

Chapter Text

It all started with scribbles in a notepad—plans for the upcoming mock exam.

Yeon Si-Eun didn’t stand out at first glance. Tired eyes. Quiet presence. Always buried in books. He was the top of his class, but invisible in the crowd—alone, not by accident, but by design. Wherever he went, there was a textbook in his hands and an earbud feeding him online lectures. His shoulders slouched from years of studying; his voice was barely heard outside the classroom.

To the bullies at Byuksan High, he looked like an easy target. Quiet. Fragile. Someone to toy with between classes.

Until they made the mistake of underestimating him.

And learned the hard way.

At Byuksan, violence was currency. The strong ruled. The weak survived by staying invisible. But Si-Eun didn’t follow either rule. He wasn’t loud. He didn’t crave power or attention. He fought like he studied—with ruthless precision. Fast. Calculated. Efficient. No wasted movement. No wasted words.

And then came Ahn Suho.

Tall, brash, always one second away from a fight. Loud in every room he entered—but impossible to hate. With a crooked grin and a soft heart hidden under the noise, Suho was the kind of person who felt too much and pretended not to care. For reasons Si-Eun never quite understood, Suho saw something in him. Something worth sticking around for.

And he did.

Then there was Oh Beom-Seok—nervous, eager, always trying too hard. Trying to be brave. Trying to be popular. Trying to belong. He came from money, but not strength. And somewhere between fear and admiration, he attached himself to the two boys who had what he lacked.

Together, they were an unlikely trio:

The silent strategist.
The rich boy with something to prove.
And the hotheaded brawler with too much heart.

They weren’t perfect. But they were real.

At least, for a while.
