The plot was definitely worth watching; I would have never thought of a news reporter who hiccups when she lies to be the main character of any show. I also liked how they tied in the fate of the main male character's parents death to the fate of the main female character's parents death--- it showed how they were connected by some unusual, spiritual forces.
I genuinely do not think that this was Lee Jong Suk's best production. He's been in much better shows. In total, he is a great actor however, he's been in better shows with better plots. As always, his acting appeared to be very authentic as he played his character really well and he was passionate in scenes where his brother was accused of being a murderer.
