I loved this drama so much, it was really interesting. What I hated so much was that we (the viewers) expected her to kill her dad's murderer more "better" like the ending was a bittersweet ending. I was pretty disappointed when I saw that she only just killed her dad's murderer like that not putting that much energy into it. also what I hated, even more, was that pildo died. a lot of people are saying it was unnecessary and I get how they think that but I think it was pretty needed for the story to end correctly. I'm not saying I liked that he died, I was also pretty disappointed because they were getting closer and their relationship was getting better. but they just killed him off like that.
