Keep in mind this is pure makjang, it was purposely made to trigger the viewers especially with Do Hyun (Soo In's husband) pathetic plot line which I see a lot of people complaining about it trying to defend Do Hyun, unrightfully though. Just like any other makjang the story kicks off with the classic move of incompetent authorities/justice system. Unfortunately, it doesn't get any better after that, it's infested with stupid characters and weak dialogue. Han Ji Hye didn't seem to be a good fit to play Soo In character by being too tame and soft spoken, she often shines more in other roles where she's vibrant, outspoken and bold. Soo In as a character lacked proper characterization and depth in the first place, she was written as a generic "very nice" girl, replacing her with any other actress wouldn't have had made a difference.
