Woo Jin is one of the standout characters in 'All of Us Are Dead,' and honestly, his arc hit me harder than I expected. At first, he comes off as this quiet, somewhat detached guy who’s just trying to survive the zombie apocalypse like everyone else. But as the series progresses, you see layers to him—his loyalty to his friends, especially Cheong-san, and his quiet bravery. He’s not the type to shout or lead, but he steps up when it matters, like during the rooftop scenes or when protecting the group.
What really got me was his backstory. The show doesn’t spoon-feed it, but you pick up on his struggles with feeling invisible, both at school and at home. It makes his moments of courage even more impactful. Plus, his dynamic with On-jo adds this subtle emotional weight—you can tell he cares deeply, even if he doesn’t say much. By the end, I was rooting for him harder than some of the 'main' characters. That’s how you know a side character’s written well—they steal your heart without trying.
