Honestly this drama is not as bad as the rating says (6.7) but its not the greatest either. If you're bored and looking for something to binge watch I'd say to give a chance.
I have never in my life been attacked by second male lead syndrome on the LAST FREAKING EPISODE. I was legit shipping Joon Woo and Mi Jo the entire time and then Jason just comes and breaks my heart at the last minute. There better be a second season where him and Mi Jo end up together too.
