Weak Hero Series: What is this story?
When every day at school becomes a war. When the line between friendship and enmity gets blurred. When you have to fight for your soul and honor…
Then a hero is born, who is neither Hulk nor Iron Man.
He is Yeon Si-eun – a quiet, introvert, topper boy, whom no bully takes seriously…
But then he does something that changes the world of the entire school.
The Battle of class one: When the topper became a fighter
The story of Weak Hero Class 1 begins with Yeon Si-eun, who is constantly targeted for his weakness. But one day, when things go out of hand – he uses weapons made of brain, science and math to protect himself.
And then the destruction of the bullies begins…
He’s not alone – he has two friends with him:
Ahn Su-ho – a strong fighter
Oh Beom-seok – a mentally challenged but pure-hearted boy
The three of them together give a befitting reply to the school gangs… but in the end there is a twist that changes the meaning of friendship and enmity.
Class 2: New school, new gang, and new blood!
Just when you think the story is over, the real test of Weak Hero Class 2 begins.
Now Yeon Si-eun comes to Eunjang High School, where there are no friends, and the enemies are even more dangerous than before.
This time her biggest challenge is a gang called Union and its leader Na Baek-jin.
But Si-eun is not the same anymore…
This time he is accompanied by:
Baku – a cocktail of brains and strength
Seo Jun-tae – a quiet but agile fighter
Gotak – a real tank that is not afraid of anyone
Now the fight is not just physical, but also mental warfare.
