This drama could easily had been a good 10 - 12 ep drama but the writer thought let put cancer story and her ex life story to stretch it to 16 ep lol. Sorry but not sorry
Wow I love how they ended the Song Hyeon and Seok Ryeo Love story. He realy did his best when she was in Pain but yeah everything not ended what we expect. It was felt so goood like she was crying cuz she spent an important part of her life with him and now she will going to start a new chapter :)
