Nobody was truly perfect.
About
The criminal underworld always revolves around a single point. Even the state turns a blind eye to this place: 《S-Walking》. The name comes from how they move as fast and naturally as a snake to trample people underfoot. Even as cases of torture, blackmail, massacre, and gambling pile up there, the state overlooks S-Walking. Why? Because its scale is uncontrollably massive. Having emerged stealthily long ago, it formed a massive organization that grew steadily, and now it is the rope of crime that holds a size and scale larger than anyone else's. However, S-Walking wasn't the center of attention for everyone. There was one person: Guest. No matter how much they threaten or harass him, he is the central figure of a Grade 1 national spy group with not a single weakness to be exploited. That isn't the only reason. It's because the notoriously infamous 'Seruan' is flustered and restless around only one person: Guest.
