Honestly, I wasn't expecting much more than a fluffy romcom. I hoped the pace would be snappy because it's shorter than the 20/24 eps I'm used to, but still more substantial than 10-min webdrama eps. But it felt like it lazed around for the first 11 episodes, and then was like "oh ****, we forgot to include the story." And there wasn't much "rom" OR "com". So what happened?

Acting: This was the best part of the show for me. Chani, Kang Minah and the supporting cast did great. I thought this was actually Hwiyoung's first time because he acted like a newbie to me. Considering his experience, he underperformed imo. He portrayed happiness and kindness well, but other emotions were a bit stiff. But even so, it wasn't bad enough to break immersion in his scenes.

Story: There was a lot of potential here. I'm always interested in the production of idols/music and Sorin (Kang Minah) had an interesting character arc set up. But none of it developed well. They don't spend any time on her decision to give up the idol dream until the end, when suddenly it was relevant again. Give her those complex emotions! It's natural for her to be conflicted about Shiwoo succeeding where she failed. Don't just throw that away with one line at the end.
The best part of the drama was Luice (Chani) for me. He had the important factors of making an unlikeable character watchable: 1)the other characters don't like him either; 2)he grows more sympathetic by the end; 3)he's unknowingly funny, like making a fool of himself without realizing it. He was the only comic relief- most of the drama was not funny to me. But I enjoyed Luice a lot.
The last three episodes were rushed and strangely dark. Some serious stuff goes down, but then they have to do another 180 tone shift for episode 14's happy ending. Considering the severity of what happened, some characters do not deserve second chances just because they feel bad (cough cough, Jooah and Dowoon). The plot left no room for their redemption arc, so it's weird everyone just forgives them and moves on.

But even though it was rushed, I could've rated this a 7.5 if not for the romance's "conclusion". As in, there was none! Maybe it's meant to be sequel bait or something, but the least they could do was get Luice and Sorin together. He doesn't confess to her and she doesn't seem particularly interested in him OR Shiwoo. What's the point? For me, I don't care about a kiss scene or whatever... it's the payoff after seeing them grow closer and care about each other! What's with this lukewarm final scene of the three of them singing together? There's no emotional payoff. Way to end it on a low note (pun intended).
