Choi Hyun-Wook is one of those versatile actor who can with his sheer acting skills make a drama a masterpiece.

What an emotional rollercoaster ride this drama gives us throughout each episodes..I laughed a lot ,envious of their musical group, cried a lot and sometimes those tears are not my tragic or sad moment but instead they are my happy moments..

I'm impressed by every cast's performances.Superb performances❤️..But Choi Hyun Wook excels in everything..He only with his expression can make you laugh like crazy and cake make you cry like crazy...(He will be the most demand actor in the upcoming future)..everything was balanced in this drama..
Comedy ,humour, thrilling scenes, mystery,family,friends, friends group, music band, school era, 2 pair of romances, Time travel everything is balanced in a way that never get you bored in any situation...What a writing and what a execution and what a performance..Truly a coming of age masterpiece.

First two episode started off amazingly that hooked you with this drama.You can feel your own self in Eunn Gyeol's character. But Time travel was basically an illogical to bring out but it's not about the theme time travel ...it's all about how they will show us and executed their plan perfectly..

Lastly , I'm missing those group moments where they just chilling around, pulling each other's legs and the nagging of grandmother, Han Yi Chang's comedy and humour ,the son-father relationship and the friends group...Hope will get to see Choi Hyun Wook' s next masterpiece just like this in the upcoming future..
