I will not say much just the necessary. The story captivated me since the beginning and the chemistry between the two protagonists (child and adults) was always on point, that said I think the drama really have a story to be a 16 episodes show. What dissapointed me was that in the end things were solved so fast that it seemed they were rushed to finish.
First, the uncle of Mun-Ha that just admitted his crimes without even think about it, went to jail and that was the end of all the accident story, we didn't saw of something happened with Ji eun's father, if he was caught or not, what happened to her brother, I kind of wanted that he could see that his daughter was the person he killed, and other thing is that the drama shows that his truck was sabotaged and he says that the accidents happened in that magnitude because of the frente system but is just this, it doesn't evolve in anything more.
Second after all this things become faded to end, around episode 10 I was kinda bored because the plot was all solved. The situation in the end was confusing because how can everyone know who she is but not herself, and she just continue doing everything she did before but the principal person of her life that is her mom (the circus uncle) just dissappears of her mind, did she just forget all her infancy? but then how is she in the same place she is today? She cannot say she was with her biological family because their memories were not changed just hers. Also for Cho-won and Mr.Ha, they were all the story saying they could not be together and then one episode they simple forget everything and start being a couple, I was passed with this because there were no development of their characters to arrive in this point of their relationship.
And for the last part I think that it lacked a lot of informatiom about Min-gi and Han-na characters, in the end we continue not knowing who Min-gi is, just that he was someone that was in his 23rd life. Is he still a shaman? Maybe a guide that take other souls that are suffering to complete their journey? We will never know.

But despite me over analyzing things it is a good drama. To be honest the soundtrack was what catched my eyes (or ears) first. I heard Colde's music Star on YouTube and that was how I came to see the drama. It is a good story to pass the time, it's new, fresh and kinda cute. I recommend you to watch and take your own conclusions.
