The music spoke. The ending mumbled.

This drama had me from the premise alone: a small-statured, big-dreaming drummer joining a band of musical prodigies. Akane’s underdog energy was irresistible — the kind of aspirational grit that makes you root for her even before she picks up the sticks. I expected romance to creep in, as it often does, but then came Naoki: reclusive, obsessive, and seemingly married to music. From that moment, I knew this wasn’t going to be a love story — at least not the kind with roses and longing glances. This was about artistry, ambition, and the messy business of finding your own sound.

Akane’s journey to discover her voice — and the band’s eventual fusion of clashing styles — was the emotional core. The creative friction, the push-and-pull of personalities, resonated far more than the late-stage romantic subplot, which felt like an afterthought. If there had to be romance, I’d have preferred the adaptation stick to the novel’s original ending with Kazushi. Naoki, written as emotionally detached (possibly neurodivergent or asexual), didn’t need a love arc. His most compelling dynamic wasn’t with Akane at all, but with Sho — the hot-headed guitarist whose chemistry with Naoki sparked more than any scripted romance. And yes, I only realized halfway through that Sho was the same actor from Cherry Magic. Oops.

While it never reached the fluffy warmth of "I Will Be Your Bloom", "Glass Heart" had far more, well, heart. Takeru Satoh’s portrayal of Naoki was quietly devastating — especially during that haunting English solo, which nearly made me swoon for someone supposedly incapable of inspiring swoons. The production was sleek, but the pacing veered into rollercoaster territory, leaving little room for nuanced character development. Naoki’s sudden emotional pivot toward Akane felt especially forced, undermining the careful restraint that had defined him.

Despite the uneven emotional payoff, Akane’s arc held firm. For a moment, I feared she’d be overshadowed by Yukino (played with quiet magnetism by Takaishi Akarii), but Akane remained the beating heart of the story. Glass Heart may stumble in its execution, but it delivers a resonant message: finding your rhythm isn’t about being the loudest — it’s about being heard.

Go in not expecting anything!

I didn't read any of the reviews before I watched this. Netflix recommended this based on my watch history. I went in blind and honestly I was in a drama mood lol. Japanese acting is either hit or miss with me but I liked it overall. Honestly the last episode is what sealed the deal. It felt like I was watching a concert instead of a drama and this is the first time I've ever appreciated whoever was the cinematographer. Then to discover they all played their own instruments? So awesome! You have villains, good people and people who learn their lessons and grow. It does leave the ending kinda open but it's enough closure for me that I'm ok even if the don't do another season. Just enjoy it for what it is and it's only 10 eps at like 40 mins a piece. I flew through them honestly.

One of the Japanese series that won my heart right away. I won't lie, I was a little scared at first because a lot of people told me how romantic J-dramas look and that they're mostly a disaster (I couldn't judge, I guess I haven't seen romantic J-dramas to begin with), but I was really pleasantly surprised and excited. The series is really beautifully done, not to mention the great songs! I also really like how it shows the real work of the singers, how they carry it all, how demanding the work can be and how much it depends on the other members of the band or staff, that it's not just about the main singer. I also have to mention that I cried like a little child during one unpleasant scene when they were waiting for the performance (we won't mention it, no spoilers) and even at the very end, when I cried through the entire last episode. I really didn't believe that a 10-episode series would grab my heart like this, but it did and I really didn't know how to move on. Maybe that's why it took me so long to write a review. But now I'm finally writing it, I remember the series with a smile and I recommend it to all lovers of romance, friendship and music. I think that this series will 100% be among the top jdramas of the year. Definitely don't miss it and give it a chance, it's worth it❤

The OST of the year

It's been a long time since I've been this captivated by a drama, even more by a Japanese one, but "Glass Heart" has to be one of the best J-dramas out there.
The cast was amazing and I can't even imagine how much hard work they put into this, learning to play the instruments from scratch. I've been a Takeru fan for years and I don't think I've ever heard him sing with as much passion as he did here, he sounds amazing. And Masaki! If I hadn't known it was him I would have never recognised him. All of them did great, I loved the band and I really hope this isn't the last we've seen of them.
And the soundtrack is superb, but that was already a given knowing all the people that helped create it. I've been obsessed with some of the songs for a month now and I really wish Tenblank would go on a world tour, because they're that iconic.
All in all, I wouldn't be surprised if I came back to rewatch it soon, because even if I've watched other dramas since then I still can't move on from it.

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.

Entendi pq chamaram de J-Trauma

Glass Heart me pegou de jeito desde o primeiro episódio. Eu nem sei ao certo como colocar em palavras tudo o que senti, mas precisava dizer alguma coisa sobre essa obra de arte.

Quase deixei passar por "medo". Vi alguém chamando de “J-Trauma” e achei que fosse ter um final triste demais. Mas felizmente dei uma chance… e acabei devorando tudo de uma vez só. Que experiência linda. As músicas, os cenários, os personagens, a história... tudo me envolveu completamente.

Confesso que temi um triângulo amoroso, mas graças aos deuses do romance, apesar de esse tópico ter surgido, não foi por esse caminho. Akane sempre amou o Naoki. E ele, do jeitinho contido dele, sempre amou ela também. A forma como eles se desenvolveram foi delicada, intensa, especial. E aquela cena do beijo? Ele cantando pra ela? Eu ainda quero chorar de amor só de lembrar.

Outro ponto que me pegou foi o Toya e o Mahiro. Juro, aquela cena no hospital confirmou tudo. Tem sentimento ali sim, eu não estou doida.

Mesmo com aquele final aberto, Glass Heart é um 1000/10. Parte de mim agradece por não terem escancarado tudo, porque meu coração já tava destruído só com a possibilidade. O resto a gente preenche com a mente, né? Kkkkk

Se você chegou até aqui, só te digo uma coisa: assista Glass Heart. É sensível, é apaixonante, é tudo. E claro… streaming na TENBLANK 🤟🏻

Une symphonie fragile qui laisse une empreinte profonde

Glass Heart — Une symphonie fragile qui laisse une empreinte profonde

Il est des œuvres qui ne se contentent pas de raconter une histoire, mais qui nous habitent, longtemps après le mot "fin". Glass Heart fait partie de celles-là.

Ce drama m’a profondément bouleversée. Ce n’est pas juste un récit sur la musique ou sur la célébrité, mais un voyage intérieur, une plongée dans la solitude, la douleur invisible, et l’espoir ténu que quelqu’un, quelque part, puisse nous comprendre.

Le personnage principal interprété par Satoh Takeru avec ses silences, ses maladresses, ses regards fuyants, ses comportements étranges incarne à merveille ce mal-être qu’on n’arrive pas toujours à nommer. Par moments, il semblait presque autiste — pas dans une représentation forcée ou stéréotypée, mais dans cette justesse troublante de quelqu’un qui perçoit le monde autrement, plus intensément, plus crûment. Son mal-être m’a profondément touché, peut-être parce qu’il m'a fait ressentir cette sensation d’être "à côté" même quand on est entouré.

Et puis, il y a l’esthétique. Chaque image est une émotion visuelle. Les scènes de pluie, en particulier, sont d’une beauté à couper le souffle. Elles ne sont pas là juste pour faire joli : elles parlent, elles pleurent, elles lavent. C’est comme si le ciel lui-même accompagnait le cheminement intérieur des personnages.

La musique, quant à elle, n’est pas un simple fond sonore : elle respire avec eux, elle crie quand ils se taisent, elle panse quand ils saignent. L’album de TENBLANK est un prolongement de cette expérience — fragile, intense, vrai.

Glass Heart ne plaira peut-être pas à tout le monde. Il faut accepter la lenteur, le silence, l’ambiguïté. Mais pour ceux qui cherchent une œuvre qui touche au plus profond, qui fait pleurer , qui résonne avec nos fêlures… alors ce drama est une perle rare.

Déjate atrapar y disfruta del proceso

Desde el primer momento es atrapante y no necesariamente te tienen que gustar los temas musicales o el rock, lo amarás en el proceso. Encontramos personajes que han logrado mostrarnos el como la pasión, la hermandad, el respeto, y sobre todo la resiliencia logran darnos esperanza para perseguir nuestros sueños.

Mediante Akane conoceremos una versión cruda y real de lo que probablemente pasamos las personas, las dudas existenciales o las comparativas que nos hacemos con otros, son esos pensamientos los que al reconocerlos y luchar contra ellos podremos liberar nuestro verdadero yo y seguir nuestros sueños.
En un sentido humano, no son perfectos, cada uno arrastra un pasado pero al hallarse juntos son el hogar del otro.

La banda en si esta conformada cuidadosamente y como dice Fujitani Naoki, cada uno produce un sonido único, diferentes a él, tanto que él los necesita para su composición perfecta. Se complementan. Fue genial ver lo que comprende ser un musico, la musa de los músicos, el amor y pasión por la música, la línea de trabajo, el proceso creativo(lo positivo y negativo), lo que transmite una canción de corazón a corazón, ese sonido que los conecta con ellos mismos, su banda y el público.

Glass Heart es una obra de arte, no pude evitar verla 2 veces y cuando pueda la volveré a ver, gracias a Netflix que salieron todos los episodios de una ...no hubiera podido esperar semanas. Me convertí en fan de Tenblank 😎♡

Los efectos visuales y musicales, todo es una obra de arte ♡ Satoh no deja de sorprender como actor y ahora como productor. Amo que el cast principal, quienes son super conocidos, talentosos y con trayectoria en Japón , ahora lleguen a mas publico internacional.

Me encantaron dos frases:
"Los prejuicios bloquean el entendimiento. Es preferible arriesgarse e ir más allá para dar la vuelta a todo lo que ya está inventado."
"Cuando encuentras a alguien que te gusta el corazón se acelera, cuando escuchamos la música que nos gusta el corazón se estremece. Las personas que amamos, la música en la que creemos, hacen ese sonido más fuerte en tu corazón. Lo hacen real. Es el sonido de la vida y nos pertenece sin ninguna duda."

Mis grandes deseos serían que:
-la novela tenga una versión en inglés porque en español es un poco difícil.
-hagan continuaciones del live action y podamos ver cómo es que Saijo Akane y Sakamoto Kazushi terminan casados así como muestran en la obra original (fuente Wikipedia Japón)
-tengan una gira mundial, por lo pronto tendrán su primer fanmeeting 11 de octubre.

Je suis tombé sur ce drama au hasard je savais pas du tout à quoi m'attendre étant pas spécialement fan de l'univers. Les deux premiers épisode m'ont mis une claque je me suis dis quel banger. Les personnages les musiques tous est magnifique même si parfois il y'a des moments assez long de flottement mais tous de même incroyable drama très touchant je ne peut mettre une note inferieur à 10/10

O Som que Quebra, Cura e Conecta???

Coração de Vidro é um drama feito para quem realmente respira música. Não importa o gênero: só entende as conexões quem compartilha do mesmo sentimento.
Eu terminei impactada com a intensidade dessa produção. A gente sabe que tudo em excesso pode quebrar… mas como não se render a um amor tão genuíno pela música 🎶🖤🎵
Um sentimento abstrato, mas que em vários momentos parecia ser quase palpável, de tão forte e presente.
Teve amor, lealdade, amizade, irmandade , mas nada da forma superficial que estamos acostumados. Foi tudo maduro, consciente, vivido por personagens fortes, decididos, que sabem exatamente o que guardam no peito.
A protagonista é um espetáculo à parte
Gritei: PERFEITA
Uma mulher que não romantizou sua dor, não se perdeu, não abriu mão do próprio brilho. Era como se, o tempo todo, ela dissesse: “Esse sonho é meu. O resto é bônus.”
Ela foi cuidada, correspondida, valorizada, amada de um jeito único, que emociona sem precisar forçar nada.
O protagonista… que atuação🫢
(LINDO, LINDO LINDO) Incrível. Me arrepiei em muitos momentos.
Ela precisava de uma chance.
Ele precisava de um motivo para continuar.
E, nesse quebra-cabeça, um acabou sendo a peça que faltava no outro (HOOOO)
Repertório? Uma perfeição.
Minha playlist agradece 🎵🖤🎶 não tem uma música ruim. Tudo conversa com a história, tudo amplifica as emoções.
O final… foi exatamente do jeito que eles sonharam. E isso basta.
O depois, deixa para depois.
NOTA: 10/10

Strepitoso

aspettavo con trepidazione questo nuovo drama con uno dei miei attori giapponesi preferiti Takeru Satō! Lui è sempre un piacere vederlo, anche perché ha un modo di recitare molto particolare, sempre un po' assorto, cupo e taciturno che colpisce sempre con il suo sguardo intenso e profondo! Qui non è da meno, conquista da subito con il suo carisma, anche se io confesso che già dalle primissime scene ne ero già rapita soltanto vedendo la sagoma della sua schiena, rigorosamente sempre coperta da cappottoni lunghi di ogni varietà!! È semplicemente unico e inimitabile! 🤩 Tra l'altro mi ha stupito molto anche il fatto che penso di non averlo mai visto sorridere cosi tanto, a differenza delle sue precedenti serie dove appunto è una rarità, direi che qui è proprio un bel guardare! 😁
Di solito le serie ci mettono sempre almeno 3-4 puntate per ingranare, e invece qui già dopo 3-4 minuti dall'inizio si parte col botto! Una buffa ragazza fuori da un concerto annullato non si perde d'animo e tira fuori la sua batteria e inizia a rullare sfrenatamente piatti e tamburi, poi di seguito dal lontano palco parte una sonata di pianoforte con un cantante che carpisce il suo sound e le si accoda...ed è proprio da lì che parte la magia e di capisce l'animo vero di questa serie!! 🤩 Non può non partire il fomento e l'adrenalina con il ritmo di queste canzoni!! 😁
La trama è abbastanza semplice e interessante, si assiste alla creazione di una nuova band e ai rapporti interpersonali che si creano tra i 4 componenti con caratteri ben distanti l'un l'altro! Il leader indiscusso della band e Naoki Fujitani che diventa un tutt'uno con lo spirito artista del suo interprete Takeru, e ci mostra un genio indiscusso della musica, uno spirito estroso, bizzarro e imprevedibile! Accanto a lui c'è il chitarrista Sho interpretato da una splendida scoperta di nome Machida Keita, poi c'è l'introverso e un po' schivo tastierista Kesushi e a completare la rosa dei Tenblank si aggiunge Akane, la buffa ragazza che tanto ha voluto Naoki per dare un po' di brio e raggiungere il giusto sound per la sua band!
La trama ruota intorno alla voglia di questi ragazzi di creare musica, trasmettere le proprie emozioni e cercare di superare sempre i propri limiti senza farsi abbattere dalle cadute che incorrono nella vita! La storia viene raccontata molto velocemente, e ti ritrovi a viaggiare intensamente con loro a vivere le loro gioie e loro dolori e a godere spassionatamente della loro musica!
Ad un certo punto della trama..."ho tremato" e ho avuto un po' paura di come stesse prendendo piede la storia, ma ho apprezzato molto in modo in cui hanno deciso di gestire l'epilogo! Se devo fare un appunto io personalmente avrei voluto si desse un po' più spazio al Villain della situazione Toya, il cantante alter-ego di Naoki, che sin dall'inizio si è posto male ma già si intravedeva fosse un personaggio molto interessante!
Per il resto la trovo una gran bella serie che ti lascia addosso tante emozioni e vale davvero la pena vedere!
