Where to start... First of all, the relationship was very HEALTHY, and if there is one thing I love about BL Dramas, it's that both main characters in the relationship are on the same page, and there will be no toxicity involved in the end.

STORY:
The story felt pretty generic in the first episode, but I got fooled when I saw episode 2 where they switched POV from Bandleader "Gun" to the School President "Tinn". With that, we not only get to see Gun's side but also Tinn's, and later a bit of the supporting characters who also had some interesting things going on. They weren't in the focus as much, but that was fine in my opinion since they were still a big part of the story.

I don't want to spoil too much about the story. I will just say that the buildup to the next "arc" was perfectly implemented.

CHARACTERS:
Gun and Tinn have very different personalities, but somehow they made them so damn compatible with each other. It's also very interesting how I first thought, "Oh, I know what kind of guy he is" - because I was so wrong. Especially about Tinn. I thought Tinn was some strict asshole, but holy shit, no. He's shy and a gay mess.

Side Characters/Ships:
With them being a band, I was initially worried they would write the rest as NPCs, just there for the music, since that's a common thing in dramas/TV shows with a music genre. But nope. Every character mattered because with one of them missing, they wouldn't be THE Band.

"Win" is the hot-headed friend who says aloud what he thinks before thinking, but he always means well and apologizes when he's wrong.

"Sound" - I didn't like him at first. He appeared like 2/3 episodes later, and my first impression was that he was some prick. But that's what the series wanted you to think of him because, in a sense, he is that. But he's also a very thoughtful boy who just wants the best for the band and has a love for music. He just takes it a bit more seriously than the other boys. He and Win are very different, but just like Gun and Tinn, even though they are so different, they are indeed a perfect match.

"Por" is somebody who, I have to admit, I didn't really feel for until like episode 8. Like, he wasn't bad or anything, he was funny, but he just got really "loud" later on for specific reasons. But I thought when he got good screen time, they did the right thing. His highlight moment was great.

"Tiw," unlike the other supporting characters, is not a band member but a member of the student council team and also the best friend of Tinn. And wow, let me tell you, he is just the BEST matchmaker ever! Sometimes I felt like he was speaking for the audience, and I loved that. Tiw and Por are also a "ship," but it happens very late, which I found very sad, to be honest. But I guess that was because Por didn't get that much attention until later. But it was alright.

"Yo" is nice and also got a little bit of a storyline, which I found very cute.

"Phat" is probably the only one with little to no story, but that's literally so basic for the drummer of a band. But then again, I felt like it was fine. He did his part in the main story and was an overall great character.

Overall, we have a great number of characters with different kinds of personalities and interests, which I always find

Other than that, we also have the parents who I find very interesting. Gun's and Tinn's mothers are so different from each other, but both work so well. I really, really loved them. They are truly wonderful parents.

ACTING:
That's something I loved the most here, actually. You can tell how well the actors work with each other.

Music:
Incredible. Not saying much. I don't understand the language, but I always have a smile on my face. Wonderful.

Oh, and the intro is also very nice!

Rewatch Value:
This has rewatch value - something I might actually rewatch in a year or so.

Dislike?
Well, I wasn't much of a fan of the silly sounds they popped in here and there. I know that's just how they produced it, but when I watched the first episode, I needed some time getting used to it, haha


TLTR;
The BL drama has a healthy relationship between the main characters, Gun and Tinn, and the story is initially generic but becomes more interesting as it switches perspectives and builds up to the next arc. The characters, including the supporting ones, are well-developed and their dynamics within the band are explored. The parents of Gun and Tinn are also interesting and well-portrayed. The acting is great, and the music is incredible, even though I don't understand the language. The intro is nice, and the series has rewatch value. The only dislike is the occasional use of silly sounds, but overall, it's an enjoyable drama.
