I know its fictional

But how does one live without a shred of survival instinct? i read this occasionally but every time wooju's too trusting and naive asf. How can you not suspect that cha guy after he gave pills that knocked you out?? Alsp who is that faceless guy that took uke to the prof? Why is he faceless? I blame everybody around wooju for this mess. For hiding secrets and whatnot that concern him.
