GAKU TANAKA
I'm Sakurashimeji GAKU TANAKA, and I'll be performing the theme song for "Kurosaki-san's Loyal Love Won't Stop."
I am truly happy to have been given this opportunity. Thank you very much. Koharu and Kurosaki
It's a bit twisted, but it's a pure relationship and various interactions. Feelings that seem to have been left behind in the distant past,
I made this drama while thinking about whether I would be able to regain it through it.
I hope that this song will do my best to color their future.

HYOGA TAKADA
I am very happy to have been given the opportunity to write the theme song for the drama "Kurosaki-san's Unwavering Love Can't Stop."
I think so! When I was creating this song, "Koi Kasubiyori," I first read the original work.
As we follow Kurosaki's awkward love life and Koharu's feelings of not being able to be honest,
You'll be drawn in and before you know it, it's morning. The song expresses such a passionate and captivating story.
I created this with the hope that it would be possible. In the story, Kurosaki conveys his feelings to Koharu "over and over again."
The clumsiness of not being able to do things well, but the strength of mind that keeps on attacking, once the spring is wound up, it keeps on moving.
The song is an analogy to a tin toy. Please listen to this song along with the drama.

Shirase Koharu (played by Toyoshima Hana)
The bright and fresh voices of the two singers in Sakurashimeji 's theme song are a perfect match for Koharu-chan and Kurosaki-san.
I thought it was Tari! If you're in unrequited love or want to remember the bittersweetness of your first love, this is a song you should listen to over and over again.
I'd love for you to come!

I am truly happy that my friend wrote the theme song for the film I am starring in.
I feel so happy and excited to see them perform live, knowing that they must have had a deep understanding of this work and carefully written the lyrics together.
I am filled with the desire to listen to Koi Kasubiyori.
I like the way Gaku sings 2B. Hyouga's singing at the end of the second chorus is the best.
is.
I feel that the honest gazes exchanged between the two of them add color to this song.
It's a really important song now and forever.
