This film was such an eye-opener - raw, emotional, and at times heartbreaking. It beautifully captured the struggles and meaning of life through the eyes of musicians. Every episode had purpose; not a single one felt dull. What touched me most was their growth - how they supported each other through pain and uncertainty. They wanted to walk away, not out of selfishness, but because they believed it was the only way to protect someone they cared about.

But in the end, they stayed - because taking the music away would've meant taking his life, too. Every song hit deep and inspiring.

Thank you for creating TENBLANK!

A true gem that comforts the soul. The cast's dedication is astounding; they learned to play their instruments for real. This authenticity shines through in the music, with amazing original songs you'll immediately search for on streaming services. It's not just a show, it's a feeling. You will not regret it !

At first, I was a little about whether this was going to be good or not. But the more I got into it and found the characters in the story, I realized how touching this story really was. And then when I found out that each of the principal actors spent over a year learning to play their own instruments and do their own vocals - wow! A little overdramatic at some point, but overall well thought out, well dramatized, well acted. I've really fallen in love with Korean dramas and since I don't speak, Korean, I appreciate the fact that Netflix is dubbing them in English. I really recommend this series.

This was a change from my K drama viewing & the Japanese have a different style when it comes to their drama. It is not so slick & stylized. There was far more emphasis on the music rather than the romance. The characters seemed more realistic. I found it interesting the intensity of these musicians for their craft.

The ML was certainly charismatic & I believed he was this flawed character. Can he be excused for his behaviour at times because he is a genius? I did not know why the FL was so taken with him as there was so many issues to overcome in being with someone like that.

The other 2 in the band contributed well to the overall story of the band. Toya from the rival band was a far more intriguing character & it was a shame after his incident we didn't get to see him more but only in the last episode. I didn't understand why he would be singing the same song as TENBLANK as their style was so different. The corrupt ex-manager was hard to fathom his interaction with the ML.

The last episode was just about the concert which I felt was a bit of a letdown.

Overall, it was a moving portrayal of a very intense industry. No wonder so many musicians die young.

Glass Heart unfolds a moving story of redemption and ambition. It's a tale of chasing dreams and confronting pasts, though at times the pacing feels rushed, compressing major developments into too little time.

The music is where the series truly soars, goosebump-inducing and masterfully composed. Its soundtrack blends emotional resonance with rock intensity. Sho's guitar sizzles with precision and flair, Kazushi's keyboard brings lyrical depth, and Akane's drumming provides the heartbeat of the band. Each performance is electrifying, culminating in powerful live scenes that feel authentic and hard-earned. Naoki's vocals elevate it all: soulful, commanding and unforgettable.

Naoki Fujitani is the emotional and narrative anchor of the series. A reclusive genius dubbed the "Amadeus of rock", he's a perfectionist haunted by a brain tumor and a brush with death. His backstory, from leaving his family to forming TENBLANK with virtuosos, is deeply layered. Takeru Satoh captures every nuance; his playful intensity, creative obsession, and vulnerability; with magnetic charisma. The writing around Naoki is exceptional, grounding the entire series.

Yet beyond Naoki, the character work falters. Akane Saijo lacks emotional nuance; her transformation from rejection to resilience feels too sudden, and her romantic arc is underdeveloped. Sho Takaoka exudes effortless stage charisma, but his character remains mostly reactive, with late emotional bursts that lack narrative buildup. Kazushi Sakamoto shows flickers of jealousy and creative tension, yet his motivations stay vague, making his clashes with Naoki feel abrupt and unearned. These characters orbit Naoki rather than evolving alongside him, leaving the ensemble emotionally imbalanced.

Despite these flaws, Glass Heart is a thrilling, emotionally charged ride. For fans of music-driven drama, it's a must-watch; flawed, but unforgettable.
