it was either character development, or he was just drunk. let's stick to character development tho to give the author more credit
(づ￣ ³￣)づ i forgot he was drunk, but he drove and did not seem so unconscious , so maybe he knew what he did and is actually a character development
or he's just good at drinking.
(this is a fictional character were talking about lel)
that adds to my point,thanks
wow sangwoo is a weaklen and damn bum , that's some character development
