Yeon Si-eun's character undergoes a significant evolution in the second season: from a withdrawn loner, crushed by guilt, he learns to trust people again and open up to them. Here are his key personality traits in "Weak Hero 2":

· Guilt-ridden: He feels guilty about what happened to Suho in the first season, making him even more withdrawn than before. At his new school, he deliberately isolates himself from everyone so that no one gets hurt because of him again.
· Outwardly cold and distant: He has a very gloomy aura, appears as a “willing outsider” and does not want to get close to anyone.
· Inside, a longing for connection: Despite his aloofness, he still yearns for friends and, deep down, wants to let someone into his life again. This inner struggle is evident in his sad, yet strong, gaze.
Hidden Strength and Determination: Behind his slight frame and quiet demeanor lies an incredible ferocity and fighting spirit. Si-eun is a true "monster" who awakens when the weak are bullied. He still uses his wits to win fights.
· Gradual Healing: Thanks to new friends (Park Hoo-min, Seo Jun-tae, and Go Hyung-tak) who melt his ice, he begins to smile again and gradually escapes the traumatic memories. By the end of the season, he is finally able to forgive himself and regain hope.

Baku's (Humin Park) character is a combination of outward cheerfulness and deep inner responsibility, which makes him a true leader and protector.

Here are his main character traits:

Radiant and cheerful: He has a very lively and outgoing personality, energizing those around him. The actor who played Baku specifically wore shorts and flip-flops in the winter to highlight this trait from his first appearance.
· Noble Protector: He has no interest in fighting for power and refused to join the Na Baekjin Alliance on principle. Baku is the school's informal guardian, stopping bullying and protecting the weak, even at the cost of his own peace of mind.
Guilt-ridden: Behind his smile lies a heavy burden. He feels responsible for his childhood friend Baekjin's violent behavior and is tormented by the trauma his loved ones suffered from conflict.
· Unwaveringly Loyal: Baku always tries to take responsibility for all his friends. He is willing to endure threats and do things he hates (like working for the Alliance) just to protect his loved ones from danger.

Thus, Baku is a complex character: behind the mask of a carefree strongman lies a man with a big heart and a heavy burden of responsibility.

Baku is a tall guy who plays basketball with Gotak and is the life of the party.

From the intimidated "errand boy": Juntae was initially quiet and submissive, meekly following the orders of school bullies (like Hyoman), fearing the consequences. This made him the most vulnerable in the school hierarchy.
· Towards a bold and determined ally: The impetus for change came after meeting Yeon Si-eun. Jun-tae began to seek his own path to the fight, realizing he no longer wanted to be a coward.
· Bravery without fists: Lacking combat skills, he compensates for this with observation and strategic mind - he becomes an "informant" in the group, collecting data on enemies.
Selfless Loyalty: Juntae repeatedly demonstrates his loyalty to his friends, sacrificing himself and taking blows for his comrades. In the series, he is even capable of engaging in a fight alone to protect a loved one.

So, Junta is a character whose strength does not come from physical strength, but from loyalty, courage (despite fear) and a sharp mind.

Junta was always in the shadows but his 3 friends made him happy, after a long time he began to fall in love with his friend Gotak

Junta is a short, smart guy who wears glasses because of his poor eyesight.

🔥 Hot-tempered and impulsive: He acts without thinking, gets easily irritated, and is ready to immediately rush into a fight if he or his friends are offended. However, over time, he learns to better control his anger.
· 👊 Loyal to the End: For him, loyalty is a matter of life and death. He's crazy about his best friend Ben, defends his honor, and is always ready to lend a shoulder to cry on, even when the odds are stacked against him.
· 🏋️ Incredible resilience: He's not one to give up. Even when losing, Gotak gets up and continues the fight, demonstrating remarkable endurance and tenacity.
· 🤝 Caring companion: Despite his aggressive appearance, he sincerely worries about his friends and is the first to rush to help when they are in danger.

Gotak is a guy who will always have your back, even if it means going into the thick of things.

Gotak was always on edge and he lacked warmth and care from someone, but he only had his 3 friends around him and he didn’t know how to communicate with girls.

Gotak is tall and slender and plays basketball.
