No Spoilers:

A broken girl meets a savior with a sad past and together they decide to take on all those who have scarred them. The highlight of the show was the chemistry between the leads.
Jung Yoo Min is made for main lead roles and she proved it in the show, while Sung Hoon charming as ever too did well.
Each and every character played their roles so well, you do end up loathing and loving them.
I was sceptical at first as the webtoon had quite many chapters and whether they will be able to get the entire story arc done in 12 eps and not rush it but they certainly hit the bullseye.
