I binged this show in 2 days!!! I was totally hooked!!! I seriously adored all of the actors, every one of them played their parts really really well (especially the young cast) !!!!!

HOWEVER, I found parts of it a little cliche, I honestly expected a better soundtrack for a show about music, and I didn't like the ending. The ending felt very rushed and like they just wanted to put a bow on top of everything all pretty without doing all the effort to get there. I actually didn't hate the love triangle in this show, I felt the time-travel aspect put enough of a twist on it so it wasn't too cliche. I also sincerely appreciate how the love triangle didn't last for the entire show like many others do. I felt like the plot got a little messy in the fourth quarter, but it was acceptable, there really is no way to make a time travel show not have plot holes and weirdness going on. I also felt like they kind of overdid it with the connections thing, like not everyone has to be connected in weird ways... sometimes people just live unrelated lives.

BUT I still found many many things I loved about this show. I loved how good the actors were and I felt like (as someone who isn't deaf and knows exactly 0 deaf people) it was good representation of deaf people and the struggles they face. I really liked
Ha Eun Gyeol's character arc, and Ryeoun's acting was quite good. He really mastered his character and I felt that he wholly cared only about the others, without a hint of selfishness (for the most part). . I also sincerely loved every single second that Ha Yi Chan was on screen (he's so hot). I felt that Choi Hyun Wook absolutely devoured this role, like there wasn't a single time during the entire length of the show where I felt like his acting was off. Same thing for Shin Eun Soo she absolutely ate up this role and perfectly conveyed her character in every single scene. Seol In Ah's acting was good, but I didn't feel the same greatness that the other actors delivered. I really can't pick anything out in particular that I thought was bad or wrong, but her vibe wasn't quite there as much as the others.

FINAL THOUGTS:
It was definitely worth the watch and I might recommend this to friends and such. It was a fantastic coming of age story and it was very touching. The time travel was much better executed than many other similar shows, and overall I enjoyed this show. I wasn't bored once!!
