    A perfect harmony of music and storytelling

    This series hit all the right notes for me-literally. The music is woven into the heart of the story in a way that made me feel like I was part of the band's journey.

    Every performance, every quiet moment between songs, felt alive and real. The storytelling is just as powerful-full of emotion, rhythm, and flow. The way the characters connect through their songs made me feel like I was right there with them, in the middle of it all.

    If you love music-driven stories that still deliver on character depth, this is an absolute must-watch.

    The unbreakable bond of music

    One of the best series I've seen in a while. Talented actors, fantastic storyline, gorgeous characters and heartfelt music. 🎵 Really touched my heart - made me laugh, cry and swoon.

    Highly recommended for anyone who feels the real, raw power of music and how it binds us all together, and likes some romance on the side.

    Piece of art, just watch it please

    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 !

    Amazing

    I've never been more pulled in by a Japanese drama for a while. The music was top notch, acting 10/10, casting 10/10. Story line 8/10. I love it so much. The ending makes it seem like there will be a season two, so I hope so, I would love to see more live connections. I loved the flash backs too. I found the play lists on Spotify, I'm really glad they decided to do that. If they can add the lyrics on there, I'd appreciate it. I do not like the voice overs, subtitled is way better with the original sound track. Main male lead needs an award for his acting in this. Super talented. Very dramatic, drummer girl was a bit cringe sometimes but overall it added cuteness. Loved it.

    The Music That Held Them Together!

    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!
