it's just good, makes me end up fangirling over seo in guk. i don't really like the romance this drama added because it's unnecessary, unrealistic, and ROMANTICIZING STALKING BEHAVIOR the only thing i like about their relationship is they're still talking about the case and stuff. I love the drama, left me crying at 3am. i think the two or three last episodes shouldn't be added, but it's ok, not that bad.
