Why Si-eun is a Character Magnet: The Psychology Behind Weak Hero’s Most Compelling Relationships

πŸ“ From My Latest Podcast Episode: A subscriber called Si-eun “literally like a guy magnet,” and honestly? They’re right πŸ˜‚ Today I’m diving deep into why every major character in Weak Hero gravitates toward Yeon Si-eun, plus tackling the big question about whether this show is actually about BL disguised as bromance.

The “Guy Magnet” Question That Started Everything

🧲 You know what made me smile like a mom? When a subscriber asked: “Why does it seem like every main character is attracted to Si-eun? He’s literally like a guy magnet!”

They also wondered if Si-eun’s constant studying might be his coping mechanism for dealing with the chaos around him – like that heartbreaking scene where little Si-eun locks himself in his room doing math problems while his parents scream at each other downstairs.

The “guy magnet” description was so perfect it made me realize something crucial: Si-eun is not regular folk. He’s anything but ordinary, and that’s exactly what draws everyone to him like moths to a flame.

The Psychology Behind Si-eun’s Magnetic Appeal

πŸ’­ Here’s my take on why Si-eun developed this unique charm, based on an amazing analysis from another subscriber:

Si-eun’s parents essentially abandoned him emotionally. They expected him to raise himself and be perfect at everything, but his father – an Olympic silver medalist in judo – was clearly disappointed that his son turned out to be this fragile, sensitive kid.

So Si-eun adapted in the most heartbreaking way possible. He became super isolated, almost monk-like, and transformed into this academic machine. He ended up living in this rigid world where he basically denied himself food, sleep, and human connection.


This totally explains Si-eun’s magnetic effect on everyone.

He’s emotionally shut down and completely self-sufficient, which creates this fascinating contradiction. He looks fragile with that pretty face and tiny build, but underneath? He’s tough as nails. That contrast is absolutely irresistible to people who recognize strength when they see it.

Why Su-ho Was Drawn to Si-eun: The Fighter’s Recognition

πŸ₯Š A subscriber once asked me something that really made me think:

“Why would Su-ho, who’s crazy busy with three jobs supporting his family, even notice Si-eun? They literally didn’t talk from March when school started until June when Si-eun went nuclear on Yeong-bin’s crew.”

Here’s what I think happened, and @Xxlove*** helped me remember some crucial details I’d forgotten:

Su-ho basically treated school like a hotel – physically there but mentally focused on work and survival. But here’s the thing about Su-ho: he’s a fighter who totally understands violence and how it creates hierarchies among guys.

What caught Su-ho’s attention wasn’t Si-eun’s pretty face or good grades. It was how Si-eun never mentally gave in to Yeong-bin’s crew.

As I replied to @Xxlove***:

Si-eun never cowered or acted scared like other bullied kids.


Su-ho recognized a kindred spirit – not physically strong, but with that inner steel that never breaks under pressure.

The show also hints that Su-ho was already watching Si-eun from the back row and knew about Yeong-bin’s crew bothering him. In that deleted scene they released, we see Su-ho step in when Yeong-bin messes with Si-eun in the bathroom.

But Su-ho didn’t actually intervene until Si-eun fought back against Yeong-bin’s crew. That’s just how Su-ho operates – he wasn’t the type to actively intervene until Si-eun made the first move.

Geum Seong-je’s Obsession: The Unconquerable Challenge

🐺 What about Geum Seong-je, who’s totally different from Su-ho but equally drawn to Si-eun?

Lee Jun-young shared some incredibly insightful details in a recent Cine21 interview about Seong-je’s eye acting – how his eyes look bored when he’s with Baek-jin but go crazy intense when he sees Si-eun.

Lee Jun-young explained:

But about Si-eun:

This perfectly explains Seong-je’s magnetic attraction to Si-eun. Unlike everyone else in his world – including Baek-jin, who he can easily dominate – Si-eun represents something he can’t reach. A challenge that makes Lee Jun-young’s Seong-je come alive.

Lee Jun-young also talked about the rooftop fight:

That’s the key to understanding Seong-je’s attraction – Si-eun is the only person who makes him feel truly alive, truly challenged. Everyone else is boring, but Si-eun? Si-eun makes his “eyes go crazy” because he’s finally met someone he desperately wants but can never fully have or control.

Baku’s Respect: Recognizing Hidden Justice

⚑ When Baku first meets Si-eun in Season 2 Episode 2 – showing up in that tunnel to save Si-eun and Go-tak from Hyo-man – he says:

What caught Baku’s attention was Si-eun’s fearless attitude. Here’s this pretty-faced boy who doesn’t flinch at all when facing Baku, known as Eunjang’s strongest fighter, but whose eyes are sharp as knives. That unwavering attitude must have impressed someone like Baku.

Later, at the chicken place run by Baku’s dad, when Jun-tae explains that Si-eun helped him against Hyo-man’s bullying – saying Si-eun is actually kind despite rumors of being a psychopath – Baku realizes there’s more under Si-eun’s cold, dead-looking eyes. I think Baku was intrigued because he sensed something like justice beneath that icy surface.

And honestly, isn’t that attractive to all of us too? How could you not be fascinated watching someone with perfect grades and a pretty face suddenly go completely insane and fight like their life depends on it?

By the way, I really love when Su-ho tells Si-eun “You’re really lunatic,” because it’s his roundabout way of saying “I genuinely like and respect you.”

Si-eun’s Academic Armor: When Studying Becomes Survival

πŸ“š Now let me tackle the subscriber’s other brilliant observation about whether Si-eun’s studying is a coping mechanism.

The answer is absolutely yes.

For Si-eun, academics represent a world he can control. Emotions are messy and unpredictable, but math is logical and has clear answers. People disappoint you and leave, but knowledge stays forever.

That scene where little Si-eun locks his door and does division problems while his parents fight downstairs is absolutely heartbreaking because it shows us his survival strategy in action. When Si-eun feels stressed or emotionally overwhelmed, he escapes into studying.

It’s his way of creating order in chaos, finding something reliable when everything else in his life feels unstable. Academic success becomes both his shield and his identity – the one thing he can control when everything else is falling apart.

The Romantic Question: BL, Bromance, or Something More Complex?

πŸ’• Now for the topic that brings out the most passionate discussions in my comments section – the romantic and potentially romance undertones in Weak Hero.

A question that pops up constantly is whether Weak Hero is actually a BL drama about boys falling in love. Let me share some fascinating perspectives on this, including a comment that really made me think.

@BayLi*** left this analysis:

There’s definitely a reason why Hyunwook looked back at the director and stopped after saying, ‘High school… love’ .. ‘Oh I should stop’ And let’s not forget that hospital scene ‘What is this feeling? The way you talk, the way you move…’ Like, come on!

The whole ‘rom-com’ label afterwards felt like a way to calm the more homophobic fans down. Honestly, for anyone familiar with subtle queer undertones, it’s pretty obvious. That series was full of them. What Sieun and Suho have is something pure. It’s love, no matter how you look at it.

This comment struck me because it highlights something important – the tension between what fans see and what can be explicitly acknowledged.

Here’s my response, which I think captures my overall take:

I agree with your comment while this drama doesn’t portray the boys’ emotional exchanges in a sexual way, personally after reading the script book I became convinced that beom-seok had sexual feelings toward Su-ho.

Of course that’s just my opinion and like you said, I also agree this drama is full of bromance undertones. But i think the production team nailed the right balance.

My Take on the Romance Question: Nuanced Love in All Its Forms

🌈 Here’s what I think makes Weak Hero so brilliant when it comes to the romance question:

This drama isn’t actually about boys’ love in a sexual or romantic way – they totally avoided those directing elements. When Director Yoo Soo-min talked about “first love,” he meant that for directing Su-ho and Si-eun’s scenes, they borrowed the back-and-forth dynamics you’d see between male and female leads in romantic comedies.

But here’s where it gets complex:

I think this drama used “first love” to describe all these intense emotions because Su-ho entered Si-eun’s isolated world as this huge presence combining parent, older brother, and friend all at once. That feeling was so powerful that it was enough for Si-eun to break out of his shell.

As I told…

The Summer of First Love: Why Setting Matters

🌞 I also loved that Class 1 was set in summer – it’s the perfect season for falling in love, whether that’s friendship love, first love, or whatever kind of love you want to see it as.

There’s something about the intensity of summer – the heat, the long days, the way everything feels more vivid and emotional – that perfectly captures the overwhelming nature of the relationships in Weak Hero.

Summer is when things bloom, when barriers break down, when people become vulnerable to connection.

The choice to set Si-eun’s emotional awakening during summer, when normal school routines are disrupted and anything can happen, was genius. It creates this sense that these relationships exist in a special, heightened reality where normal rules don’t apply.

Why the Ambiguity Works: The Beauty of Undefined Love

✨ What makes Weak Hero excellent is exactly what Park Ji-hoon said – one of the best parts of watching is the bromance between characters. The directors didn’t rush to define the boys’ emotions and left room for viewers to imagine whatever they want.

This creates something beautiful: a space where different types of love can coexist.

  • Some viewers see deep friendship and brotherhood
  • Others interpret romantic undertones
  • Some find bromance subtext in the relationships
  • Many see elements of all these things simultaneously

And they’re all valid interpretations because the show was crafted to support multiple readings without invalidating any of them.

If the creators had tried to capture those intense emotions with specific words and definitions, it wouldn’t have become such a heart-fluttering drama. Instead, they created something that speaks to the universal experience of intense connection that transcends easy categorization.

The Magic of Si-eun’s Magnetism: A Complex Contradiction

🧭 So in conclusion, Si-eun’s magnetic charm comes from being:

  • Unbreakable despite appearing fragile
  • Violently capable under his cute, cat-like appearance
  • Deeply loyal while completely isolated
  • Intellectually superior yet emotionally stunted
  • Self-sufficient in a way that’s both impressive and heartbreaking

He’s definitely not “regular folk” – he’s this fascinating contradiction that draws people in because they see something in Si-eun that they need or want for themselves.

Each character is drawn to a different aspect of Si-eun’s complexity, which is why his magnetism works on so many different personality types.

Final Thoughts: The Art of Undefined Connection

🎭 The magic of Weak Hero lies in creating these complex, layered relationships that can be interpreted in tons of different ways, letting every viewer find their own meaning in the connections between these characters.

Whether you see the relationships as:

  • Deep platonic friendship
  • Romantic love
  • Brotherly bonds
  • First love in its purest form
  • All of the above simultaneously

You’re not wrong. The show was crafted to support all these interpretations because real human connection is often too complex for simple labels.

Si-eun’s magnetism works because he embodies this complexity – he’s a character who can mean different things to different people while remaining fundamentally true to himself. That’s the mark of truly great character writing.
