why isn't anyone using a gun here ? like if you want him dead lmao

Those countries typically don't use guns often. It is usually knives and bats.

I hope that bear isn't up to something worst this time around,something smells fishy just can't trust him

A civilian owning a gun is illegal in south korea that even mobsters don't possess it. I dunno the full detail of their gun law but maybe the author is avoiding depiction using guns
