People who gave 1 point should finish the show. Honestly, at first I did not understand the subject because I haven't read the webtoon. I continued watching and the show really amazed me. It made me think about every single person's unknown inner world. One episode I hated one character and I was like die right now you are so annoying. In the other I cried for that character and prayed for him/her not to die. I loved watching them become a family. Character developments, understanding all of the characters' inner worlds step by step was amazing. In the beginning there was scenes about past and they are confusing I agree but you'll see that they are puzzle pieces and in the end they would complete the puzzle.
