A charming drama with a great message. I'm so glad I didn't pass this one up.

Acting/Cast: This drama has a great cast with acting that feels very natural. My favorite is probably Choi Hyun Wook (최현욱) and his portrayal of his character, Ha Yi Chan. I loved watching him on screen. He is such a strong and unique male lead - he's pure, joyful, passionate, tough, caring, and childlike. I keep thinking of that scene where he randomly starts spinning around and yells "TORNADO" for no reason. His character was such a breath of fresh air - no angst, all fun. His chemistry with Yoon Cheong Ah seemed so organic and the way his relationship with Ha Eun Gyeol developed felt realistic and heartwarming. I would say Choi Hyun Wook is this drama's MVP with Seol In Ah coming in at second. The entire cast just seemed like they were really enjoying their time while filming this drama and watching them have fun made it so much more fun for me. However, I would say the weakest link in this area would be Ryeoun (려운) who plays the male lead, Ha Eun Gyeol. While his character was written well, his acting was noticeably weaker than the other lead actors. He didn't have that effortless, natural feel to his acting that I felt while watching the others. Fortunately, this did not hurt his chemistry with Ha Yi Chan. 8/10

Writing: The characters are extremely well written and developed. The plot is interesting. Because it wasn’t predictable, it kept me engaged. I don’t think I’ve seen a drama with a plot and characters quite like this one. The story had a good progression of events and good pacing. There are only a couple issues I could point out in this area: One is towards the end of the drama - there is a scene that shows what had happened in the original timeline of events, but it feels a little jarring and I had no idea what was going on at first. I thought I had skipped an episode. The other issue is the ending itself – it went in a direction I did not expect, which isn’t necessarily a bad thing, but I felt it was like an alternate or fake reality because it seemed like too much of a change and more on the unrealistic/idealistic side. 9/10

Direction/SFX/Music: This is definitely a well-produced drama. The special effects were good, the music was good, the art was good, the styling, even the name of the band. Like I mentioned above, there was a scene toward the end that felt jarring. I would have shot it differently, like with a filter and effects to indicate that it was a different timeline of events. There was also another scene toward the end that involved a bad case of staring that I felt didn’t fit or feel authentic to the situation. However, these are just minor gripes. 9.5/10

Entertainment Value: A binge-worthy drama for sure. The fantasy aspect gives it a bit of mystery and the characters are so well written and acted that I just wanted to keep watching them. The fun vibe of this drama also makes for a fairly stressless watch. The ending though, caught me off-guard (like I mentioned before) and caused me to feel some kind of disconnection with the story. 8/10

Overall, I gave this drama an 8.5/10 due to my issues with the acting of the main male lead and the ending. This drama has a wonderful message about family, friendship, life, and self-acceptance. It’s very encouraging and healing while being entertaining. Also, I love the sign language aspect of this drama and how integral it is to the plot. I really like the direction they went with it.
