Additional Info.

​"Weak Hero carries the genre characteristics of an ""Iljin-mul"" (a work focusing on delinquent school gangs), but it avoids excessive depictions of glorified delinquent behavior, a common criticism of the genre. This is because the main character, Yeon Si-eun, is portrayed as a diligent student primarily focused on his studies. The drama adaptation, Weak Hero Class 1, is based on the original webtoon but stands as an independent work with its own original storyline. While the webtoon centers on Yeon Si-eun’s middle school days before entering Eunjang High School, the drama changes his age to a first-year high school student, with the events of his middle school life dramatized against the backdrop of Byeoksan High School. Additionally, the drama introduces entirely new characters who did not appear in the original webtoon, such as those connected to a runaway family and gang members like Jeon Young-bin and Kang Woo-young. Episodes involving these characters are unique to the drama, creating original storylines that expand beyond the scope of the source material. "​
