Great, great, great...

Great show, great acting, great music, great chemistry and characters. I was captivated by this magic, I became a Tenblank fan in a minute. Great musicans and singers.
The series portrayed the personality and inner world of a true genius in a truly realistic way, In my mind, a genius, a true artist is exactly like Naoki Fujitani. Satoh Takeru gave a brilliant performance, his acting and performing arts were at such a high level, I have rarely seen anything like that earlier. Among other things, that's why this production worked so well. Satoh Takeru is a genius for me and his voice... amazing.
I loved all the characters, all the bandmates, Kazushi (he was my favorite, I secretly hoped Akane would choose him, even though I was happy for Akane and Fujitani's love), Takakoka, Akane, they were so loveable, cool, special and charismatic. I really liked how they connected each other, their unique stories that brought them together, and how they stood by each other until the end. The ups and downs, in joy and sorrow, in success and failure they were one family, one invincible team. I would definitely mention the roles of Toya and Yukino, they really fit into the story and made it even more interesting.
What's a bit negative is that I didn't feel a huge breakthrough with Akane's character, I often felt the character was a bit boring and didn't develop much. Akane's character could have had a lot more potential, but in the last part, she really came to life.
The series showed what the power and love of music really means, and how to make a huge impact.
Another plus point is that it was really nice to hear the familiar song (Hikaru U.-First love) from Satoh's previous successful series, I really like it when similar references appear in a series. :)
I am very grateful to the creators, the actors and the entire crew for this special and lasting experience. Music is the cure for everything.

Boom went my heart

Love it all !! Cried a bit. Of course.

Love that it didn't finish on a sad note. Hoping for a follow up, and yet... this unfinished business also feels good. Stirs my fragile, glass like heart as never before.

I absolutely recommend to anyone who loves music shows. The acting, the production, the storyline, everything works together to enhance the music. And that music just transports you as it permeates every nook and cranny of the show.

On a side note, reminds me a bit of the melancholy in Nana, with the dynamism of One OK Rock...
A drama I'd gladly binge watch again.

Definitely stole my heart

Satoh Takeru is my favorite actor, so my expectations for Glass Hearts were high, and this film absolutely delivered. From the very first scene, I was captivated. The rain, the music, the subtle yet powerful expressions, it immediately set the tone and I knew I was in for something unforgettable.

The story is beautifully crafted, with moments that touched my heart and even brought me to tears. What stood out most was how deeply the cast embodied their roles, you don’t just watch their emotions, you feel them. Every performance felt raw and genuine, pulling me further into the world of the film.

And the music, wow!. It wasn’t just a soundtrack, it was an experience. Each note seemed to echo the emotions of the characters, making the story resonate even more. I’ve already fallen in love with it and it’s going straight to my playlist.

Glass Hearts is more than just a movie, it’s an experience I know I’ll return to. It definitely deserves a re-watch and has already secured a spot among my all-time favorites.

Maddeningly Good

This show made me mad. Not because it was bad or disappointing (like, frankly, so many of its peers), but because it got me. Hit me right in the heart, and I wasn't expecting it.

If you've read any of my reviews you'll know I carry a certain cynicism about Japanese live-action. I often find it to be cartoonish, awkward, and pointless. Countless experiences with shows like these has built up an armor for me, a way for me to relegate any new j-drama as a fun but ultimately shallow pass time, like a Netflix doc that stretches a few too many episodes. So I was caught completely off guard when Glass Heart demanded my attention immediately and didn't let go. Even a frankly cliche few opening minutes carried some magic in it, some hint of secret sauce which Netflix has been using to raise the bar on k-dramas in recent years. And as the show started to weave its plot, to develop its characters, to hint its themes, I was bewildered.

This show is undeniably a j-drama. Traces of their DNA is scattered across every episode: over-earnest protagonists, a genius male lead to outshine the rest, infectious angst, and abrupt monologues in which a character seems to blurt out their deepest complexities like a self psychiatrist. And yet here we find an extra layer of subtlety, a necessary injection of hope and ambition, and most importantly an idea. To make everything worthwhile they've managed to build the show around a group of core ideas, intrinsic facets of the human experience which bear exploring. My unshakeable hate for the "quirky genius ml showing fl the light" trope was finally toppled by the fascinating motif that "the sound of a genius makes ordinary people miserable." What a fascinating, resonant message. I'm so upset.

I have a friend who hates the movie Up. She calls it emotional manipulation. Finally I understand how she feels, because I was swept up so swiftly and completely into the emotions of this show that I couldn't help but feel offended by its audacity. It left me with the same hollow wonder that Your Name did, a certain gaping hole where a mountain of feeling had just carved its way through. I resent it. But I cannot deny that it is the foundation of a truly outstanding show. Well done.

Drama Review: Glass Heart

Glass Heart delivers a very strong and engaging storyline, filled with emotional conflicts, betrayal, and a well-balanced romance. The romantic elements are handled naturally—not excessive or overdramatic—so they never ruin the flow of the story. Instead, they complement the main plot effectively.

Another strong point of the drama is its excellent OST. The songs are powerful and memorable, enhancing the emotional weight of many scenes, especially during the musical and concert moments.

Takeru Satoh’s performance stands out as one of the highlights of the drama. His acting is intense and convincing, particularly in the concert scenes, where his charisma and energy feel incredibly real. His total commitment to the role is clearly visible, showing the effort he put into portraying the character.

However, one noticeable weakness of Glass Heart lies in its ending. The conclusion feels somewhat unresolved, which is a common issue in many Japanese dramas. Instead of giving a clear and satisfying closure, the ending leaves too much open to interpretation, which may leave some viewers feeling unsatisfied.

Overall, despite its flawed ending, Glass Heart remains a compelling drama thanks to its strong story, music, and dedicated performances from the cast.

It's Amazing

Great acting! Great story! Amazing music! One of my favourite series! So captivating, this show didn't disappoint! I won't say any spoilers, you'll have to watch it! If you're a musician, I strongly recommend giving this show a watch. There were many points where I felt inspired and motivated and emotional. This shows music and the life behind it in a beautiful way. It covers a lot of different topics, I would say there is something for everyone to enjoy. I'm now going to listen to the soundtrack!

I feel like it's a drama one can relate to...

I feel like it's a drama one can relate to even if you're simply an ordinary person. I don't know how to explain it but I feel like if we think deeply about it, there are characters in the show we can relate to somehow. We might not be geniuses nor talented individuals but we can relate on their struggles. The music just resonates deep inside. Personally, for some reason, I can relate on how we just simply wanted to be heard, although I don't know if the other viewers also can find this theme in the drama. It also made me think on how short but beautiful life can be internally. Sorry. I just want somewhere where I can write how much I love the drama. And how I wish that there could be more dramas like these. I love their bond. Or maybe I am simply biased because I love good music and band story. Although there are parts in the story that I might find a little bit cringey but the overall is actually good. The music, I can totally vibe in it. The actors' performances are all amazing and I admired them more for their dedication when I found out how they even attended lessons for these. I will rewatch it simply because I want to hear the music again and again and watch the artists perform. Also I like the emotional parts. Made me totally cry.

The Soundtrack Saved the Story, and I’m Not Mad About It

I absolutely LOVED Glass Heart! It’s a full 9/10 from me. The plot did get a little messy at times, but honestly, the AMAZING MUSIC made up for it. Every song, every performance, every little melody just pulled me right in. As a total music junkie, this show had me hooked from the very first episode.

The musicality was insane — like, genuinely top-tier. You can tell everyone involved knew what they were doing. And yes, the fact that all the actors are super good-looking definitely didn’t hurt either 😅 It just made the whole experience even more fun to watch.

Now… my only real complaint is the romance subplot. I don’t think it was really needed. I went in thinking the relationship between Sajio Akane and Fujitani Naoki would be this wholesome mentor-mentee thing, but it got weird fast. Their chemistry didn’t really land for me — honestly, Naoki had way better chemistry with the guitarist Takaoka Sho (just saying 👀).

Still, despite the messy story moments, Glass Heart completely won me over. The music, the energy, the cast — it all just worked. Honestly, a good rewatch for the music and performances, not the storyline though in my opinion 🤷🏾‍♀️.

Just five minutes into the show and I was completely hooked!

The very first thing that captured me was the music. I had been going through a slump and stumbled upon this drama with no expectations at all. I knew almost nothing about it except that it involved music a band and Takeru Satoh as part of the cast.

What surprised me most was how deeply the show speaks through its smallest moments. Even a quiet gesture carries meaning and every emotional thread is answered through the songs. The music is not only a backdrop but a voice that adds depth weight and clarity to the story.

I am loving the entire soundtrack. It lifts the drama and gives every scene a pulse that stays with you long after it ends.

Bello, significativo e pieno di bella musica ed immagini...ma

Un bel drama di stampo quasi occidentale sul mondo della musica con al centro un genio musicale e le persone che lo circondano tra cui una dolce batterista. Trama prevedibile ma sempre bella, con la giusta dose di dramma e musca....oggttivamente mi è piaciuto tanto e avrei voluto veramente amarlo, davvero, ma non sono riuscita a lasciarmi coinvolgere del tutto perchè non trovavo credibile l'attore protagonista. Ma non per colpa della sua recitazione, tengo a precisare. Ma perchè l'avevo appena visto in Marry my husband and An incurable case of love. Per me lui era Quei personaggi ancora nella mia mente. Così ho tenuto per il second lead più che per lui.

A bit contrived—but full of heart.

When I first started watching this, I was really put off by how overproduced and clean it was. I tend to prefer film that aims for a more realistic vibe over this sort of pristine, highly polished look/sound. I also had the same issue with the plot; it was just really hard to get genuinely invested in something so clearly contrived to bring about a particular final result. That said, there is an earnestness to this show's production that starts to come through, and I think that's what kept me interested. This show clearly wasn't produced just to look/feel good, but with a very specific artistic intention in mind. In spending some time going through BTS clips and learning more about Takeru Satoh's process as co-producer, I found a lot to appreciate about this work as a passion project, and have developed an annoying love for it despite how ridiculously contrived some of it is (the yacht scene in particular comes to mind). Add to that the final episode—literally just an entire live show from start to finish—and Naoki's extremely well-written monologue about why we make music (and art more broadly) that genuinely resonated with me on a profound level—I had a pretty good time all things considered.

Something I definitely want to mention is how authentic all the music in the show and its associated performances were. While they of course didn't write and produce the music themselves (it was the combined effort of 26 brilliant artists from all over the industry), the actors all put tremendous effort into learning their instruments to be able to actually play while acting, which, beyond just being a really impressive feat, gives this show a uniquely authentic aura that I wouldn't have expected after the pilot.

I could say a lot more about this, but anything more would probably wind up repetitive, so I'll keep it at that. If you're a musician, you will almost certainly have a good time with this, especially if you're willing to overlook a few contrivances. 7.5/10
