Oh Joon-Yeong is a survivor of the zombie apocalypse. He is the second smartest students in school and has a bit of a mean streak. He's caring and resourceful but he can't help but be a bit overly cocky and mean sometimes. He's quiet and likes to observe others rather than join in on stuff unless he needs to. He can get a bit jealous. Being the quiet, nerdy type he's not used to getting attention over some of the other boys.
