I seriously loved this drama soooo much!!! It served exactly what i wanted. Teen musical fantasy romance. everything was on point honestly. And it made me cry like I've never before. No lagging, no boring episodes honestly!! But at the end i felt like they could've shown more about their future lives. And also they didn't show On Eun Yu's parents i wish there will be a second season!!! I loved the bond between Ha Eun Gyeol and Ha Yi Chan so freaking much!!! And I didn't expect Choi Se Gyeong to be a time traveller too fr and The end was so awesome!!! OVERALL I'D RECOMMEND TO WATCH IT COZ I'M GONNA REWATCH IT TOO!!!
