Don't watch this

If you haven't, don't watch this drama, it's so disappointing, everything went downhill from episode 5, it had potential but the plot was just too repetitive,carried on because of the face card of the male lead. Also the OST was supper annoying, in every scene there was a background music, I became confused if I was watching a musical or not. I need justice for the Second Female lead, this show is a lesson in how not to waste such a good character.
