Synopsis of Weak Hero
Yeon Si-eun is one of the top students in his class, ranking in the top 1%, and cares about nothing but studying. He is physically weak, but he doesn't back down from the bullies in his class, led by Jeon Yeong-bin. To defend himself, he relies on his quick decision-making, his knowledge of physics and the objects around him. The series focuses on the school and on how rivalries among classmates escalate into fights. Written and directed by Yoo Soo-min, the story follows a boy who just wants to study in peace while the pressure from his tormentors keeps growing. Park Ji-hoon stars in the drama, which airs on Wavve and, since 2025, on Netflix as well.
