For core Weak Hero fans who’ve been dying to know what went on behind the cameras, you’ll get to discover some interesting parts you never knew about.

Director’s Creative Inspirations That Will Blow Your Mind π¬
1. The Hermann Hesse Connection: Si-eun and Su-ho as Sinclair and Demian
π₯Ί You know what completely floored me? Director Yoo Soo-min revealed that he conceptualized Su-ho and Si-eun’s relationship based on Hermann Hesse’s classic novel “Demian” – specifically the dynamic between Sinclair and Demian.
The director even planned to include a line when Su-ho mistakenly arrives at Si-eun’s house:
What would have happened to that boy’s world if Demian had never come to find Sinclair?

This literary reference explains SO much about their relationship dynamics. In Hesse’s novel, Demian is the mysterious older figure who awakens Sinclair to a deeper understanding of himself and the world. Su-ho literally serves this exact role for Si-eun – awakening him from his isolated, academic shell into a fuller experience of friendship, loyalty, and emotional connection.
2. The Evangelion Inspiration: Si-eun’s Breakdown Scene
Here’s something that made me go back and rewatch Episode 1 immediately: The director wrote Si-eun’s violent outburst against Yeong-bin’s crew while watching Shinji’s breakdown scenes from the legendary anime “Evangelion.”

Even someone like me with minimal anime knowledge knows Evangelion as a 20th-century masterpiece, and I knew enough about Shinji to understand this reference. After looking up Shinji’s breakdown scenes, I completely understood what vibe inspired the director when creating that devastating moment where Si-eun destroys Yeong-bin.
The parallels are actually striking – both Shinji and Si-eun are isolated boys trapped in their own shells, dealing with intense loneliness. Shinji falls for Kaworu, while Si-eun’s first love is officially confirmed by the director to be Su-ho. Both characters have these explosive moments where their suppressed emotions finally erupt into violence.
3. The Bromance Blueprint: From Baku-Si-eun to Su-ho-Si-eun
The bromance atmosphere between Baku and Si-eun from the original webtoon was adapted for Su-ho and Si-eun’s relationship in the drama.
This explains why their chemistry feels so natural and well-developed – it wasn’t created from scratch but carefully transferred from an already established dynamic in the source material.
4. The Seok-dae and Yeong-i Love Story
In the script book, Seok-dae and Yeong-i are actually portrayed as being in love with each other. This adds another layer to Seok-dae’s protective behavior toward Yeong-i that we see throughout the series.

Deleted Scenes We Never Knew About π₯
The Club Scene: Yeong-bin’s Crew Discusses Su-ho and Si-eun
You know that club scene where Yeong-bin talks about how Si-eun’s soul can’t be broken no matter how much they bully him? The original script had Jung-chan saying something much more explicit:
No… lately that bastard Yeon Si-eun seems really crazy. What’s with that fucking pen… what does he think he’s going to do, that little shit… But why does Ahn Su-ho keep covering for that bastard? Are they dating?
This dialogue was adapted from a webtoon scene where Beom-seok secretly photographs Su-ho and Si-eun walking together and shares it with other bullies, asking “What’s their deal exactly?”
This was cut from the final version, but it shows how even the bullies were picking up on the intense connection between Su-ho and Si-eun.

Yeong-i Confronts Beom-seok’s Family
This scene is already somewhat known, but in the script book, after Su-ho falls into a coma, an explosive Yeong-i runs to Beom-seok’s house and blocks the car carrying Beom-seok and his adoptive father. Beom-seok jumps out and confronts her, and according to the script, he actually slaps Yeong-i across the face.
How the Actors Prepared: Character-Appropriate Study Methods π
What I found fascinating was how each actor’s script preparation method perfectly matched their character:
Park Ji-hoon (Si-eun): Went to study cafes (very common in Korea – quiet cafes specifically for studying) and meticulously analyzed the script line by line, even considering how his scene partners would deliver their lines. So perfectly Si-eun π
Choi Hyun-wook (Su-ho): Simply read all his dialogue out loud and grasped the overall flow. Classic Su-ho – straightforward and practical π
Hong Kyung (Beom-seok): Casually read through everything and accepted it based on what felt right to him. Fitting for Beom-seok’s impulsive nature π
Emotional Moments Behind the Cameras π
Choi Hyun-wook’s Real Tears
In Episode 7, when Su-ho visits injured Si-eun at home after finding Yeong-i and fighting in Si-eun’s place, Choi Hyun-wook actually cried real tears during filming. This was the scene where Su-ho comes to check on Si-eun who’s been studying at home with his own injuries.

Hong Kyung’s Realization
Hong Kyung said something that gave me chills:
I didn’t realize how much Si-eun and Su-ho truly loved each other until I read the script book. They really were so devoted to each other.
Even Beom-seok’s actor was moved by the depth of their bond when seeing it written out in full context.
The Rolling Paper Messages That Broke Hearts π
The actors wrote messages to each other as their characters at the end of filming. Here are the most devastating ones:
To Su-ho:
Yeong-i: “Hey, wake up, idiot! I’m making money. Your noona will buy you meat. Grandma and I are waiting. Wake up when it’s time, you bastard.”
Woo-young: “It was nice to meet you.”
Seok-dae: “Stop showing off.”
Beom-seok: “I really admired you. I loved you so much. I’m sorry. I’m really sorry. Su-ho…”
Jung-chan: “Remember my name! I’ll let it slide just once.”
Tae-hoon: “Let’s be friends!”
Si-eun: “I want to go back to that time.”
Su-ho (to himself): “I think I’m going to wake up.”
To Si-eun:
Su-ho: “You’re doing well on your own, right? -Guardian Angel Su-ho-“
Beom-seok: “Si-eun… I’m sorry. I’m really sorry.”
Clearing Up the Su-ho Controversy: Why He Hesitated to Help Si-eun π€
Many subscribers were disappointed when Su-ho initially refused to help when Beom-seok asked him to rescue Si-eun from Seok-dae’s crew, saying,

“I’m not that close with him. Tell a teacher.”
Choi Hyun-wook addressed this directly in an interview:
I discussed this scene with the director too. Why would Su-ho say this? The reason was really simple – they genuinely weren’t that close yet. Su-ho has this one-dimensional side to him. Rather than overthinking, at that moment they really weren’t that close, he was annoyed at being woken up by Beom-seok, and he had to go to his part-time job later, so he was thinking ‘Do I really need to go all the way there?’ It was a series of practical thoughts.
This explanation actually makes Su-ho’s character more realistic – he wasn’t being callous, just honest about where their relationship stood at that moment.
The KakaoTalk Messages We Could Barely See π±
While this isn’t from the script book, I wanted to share something fans have been curious about – the actual KakaoTalk conversation between Si-eun and Su-ho that flashes briefly on screen. By enlarging the screen, here’s the direct translation of their chat:
Su-ho: “Where are you? Going to eat first?”
Si-eun: “Yeah, you were sleeping so I came first with Beom-seok”
Su-ho: “Wow… traitor… stay right there, don’t move, I’m rushing over”
Si-eun: “I just left though?”
Su-ho: “Ah shit, wait!!!”
Based on the timing of these messages, it looks like Si-eun and Beom-seok went to the school cafeteria to eat first while waiting for Su-ho π₯°

Why This Matters: The Depth Behind Every Choice
Reading the script book made me realize how much thought went into every single element of Weak Hero Class 1. From literary inspirations to anime references, from deleted scenes that would have made relationships even more complex to the actors’ deep understanding of their characters – everything was intentional.
The most beautiful part? Even the creative team was discovering new depths to these relationships as they worked. Hong Kyung’s realization about Si-eun and Su-ho’s love, the director’s literary framework, the careful adaptation of webtoon dynamics – it all shows how collaborative storytelling can create something that resonates on multiple levels.
These behind-the-scenes insights don’t diminish the magic of what we saw on screen – they enhance it. They show us that the emotional impact we felt was crafted with incredible care and artistic vision.
