Weak Hero Class 1 (Korean: 약한영웅 Class 1) is a South Korean television series written and directed by Yoo Soo-min with Kim Jin-seok and Park Dan-hee, starring Park Ji-hoon, Choi Hyun-wook, and Hong Kyung. It is based on the Naver webtoon Weak Hero by Seopass and Kim Jin-seok (Razen), which was published in 2018. The first three episodes premiered at the 27th Busan International Film Festival, which was held from October 5 to October 14, 2022. The first season was released on Wavve on November 18, 2022. The second season will be released on Netflix on April 25, 2025.
Yeon Si-eun is among the top 1% of students in his class and is not interested in anything except studying. Though he is physically weak, he does not back down from the bullies in his classroom led by Jeon Yeong-bin. Using his quick decision-making skills, his knowledge of physics, and the objects in his surroundings, Si-eun protects himself from their escalating acts of violence. But when he gets in grave danger, he receives help from Ahn Su-ho, the strongest fighter in their class, and Oh Beom-seok, the tormented son of an assemblyman. The three become friends as they try to survive a high school life full of violence and learn what it truly means to be strong.
It was announced by Jaedam Media in May 2021 that they had reached an agreement with Playlist to co-produce a drama adaptation of the popular Naver webtoon, Weak Hero. It was later confirmed that Shortcake, the studio co-founded by director and screenwriter Han Jun-hee (Netflix's D.P.), would also be producing the drama. Yu Su-min, who had recently won Best Film at the Mise-en-scène Short Film Festival, would direct and write the series while Han would serve as creative director. For the action choreography and stunts, martial arts director Heo Myeong-haeng (Vincenzo) would direct and Ahn Ji-Hye (Squid Game) would serve as art director. The original soundtrack would be produced by Primary.
To create the gloomy and cold atmosphere the titular character is known for, Park Ji-hoon revealed that he took inspiration from Won Bin's performance in The Man from Nowhere (2010) as well as Kwon Sang-woo in Once Upon a Time in High School (2004). The climax at the end of Episode 8 is a direct homage to the final scene in the latter. He also lost over 10 pounds of muscle to achieve Si-eun's weak appearance. The cast also attended action school together for several months so they could safely film the intense action sequences.
In an interview to the press on November 30, 2022, Director Han Jun-hee went into depth about the casting process for Weak Hero: Class One. Han had previously stated that they wanted to "invite actors who have great energy and could lead the next generation of Korean dramas and film." He said Park Ji-hoon, Choi Hyun-wook, Hong Kyung, Shin Seung-ho, and Lee Yeon are all new actors who have been working a long time in film, dramas, and on stage. He believes Weak Hero to be an opportunity to introduce these actors (to a wider audience) and serve as a beginning as they go on to stand out in many works in the future. On the casting of Park Ji-hoon in the lead, Han revealed that the idol actor was originally suggested by shotcake CEO and co-founder Lee Myung-jin. Lee was amazed with Park's performance in At a Distance, Spring Is Green (2021) and Han found it amazing as well when he viewed it. After reviewing more of Park's work and interviews, he was convinced he could show various faces and wanted to see if one could be that of a universal student in his late teens. He believed director Yu felt something similar when the suggestion was brought to him. Han went on to further praise Park as "the only actor in his 20's that could create such an atmosphere" and commended his great attitude and consideration for the staff on set. On Choi Hyun-wook's casting, Han said that he first saw him in Taxi Driver (2021) and was curious about him, but it was his appearance in Racket Boys (2021) that made him call right away as he believed that Choi would become a difficult actor to get a hold of. Overall, Han stated, it was intuition and he found it fortunate that this cast was able to take the drama.
Park Ji Hoon will be back for his titular role for the second season along with the actors: Ryeoun, Choi Min-young, Yoo Su-bin, Bae Na-ra, Lee Jae-min, and Lee Jun-young.

Kim concluded by saying that Weak Hero is "the best well-made work in the second half of 2022, with the story, directing, acting, and action." Park Jin-young of JoyNews24 wrote that the series "enhances the sense of reality by containing the worries that everyone has experienced at least once in their adolescence, such as the bond with friends, a sense of belonging somewhere, and the desire to take a step forward for a better future." Gong Hee-jeong, a drama critic, said, "Although the action scenes are stimulating and horrifying, the point that makes us think about the faults of adults beyond children's violence by sufficiently capturing the position and inner feelings of each character stands out." A culture critic, Jung Deok-hyeon, analyzed, "At the point when you think about what kind of conflict there will be a new sense of immersion is formed as problems within the children's relationship erupt." Several Korean medias dubbed Choi Hyun-wook's character Ahn Su-ho as the "Fighter of Loyalty".
