Netflix released the official poster and trailer this week for its coming series Weak Hero Class 2, the sequel to the 2022 hit Weak Hero Class 1.

Portrayed by Park Ji-hoon, Yeon faces off against a mysterious new rival, Geum Seong-jae, played by Lee Jun-young. In the trailer, Yeon says remorsefully, “Su-ho, I got into another fight. I’m sorry,” hinting at the unresolved scars from his past.
Having lost his smile and become a self-imposed outsider, Yeon struggles to stay unnoticed, but disturbing rumours soon target him.
