This show was amazing and I loved everything about it, especially the sorry line I have no complaints except for the fact that to me the main couple was kind of boring because they didn't really interest me. I liked Ha Yi Chan and Cung Ah more they were interesting and everything about their love story is just so cute. Another thing I didn't really like I that when Eun Gyeol came back to the future everything was different and now they were these rich people and I guess that's what happens when you change the past but I just feel as if it was sad that those sweet moments they had in his childhood technically didn't exist anymore. Also, the story doesn't make sense if Eun Gyeol went to the past and altered the future then when he came back to the future shouldn't he not remember his old childhood and now remember a new version with all the changes he made. Other than does small things the story is amazing and I would definitely recommend this.
