Omoinotake's "love song" to be featured in new film starring Win Morisaki and Koji Mukai
Omoinotake's new song "Gravity" has been chosen as the theme song for the film (LOVE SONG), co-starring Win Morisaki and Koji Mukai (Snow Man), which opens on October 31.


(LOVE SONG) is a Japan-Thailand co-production directed by Champ Weerachit Thongjila of Thailand, who also directed the globally popular BL drama "2gether." Morisaki plays Sota, an overly serious researcher, while Mukai plays Kai, Sota's first love who is a musician and photographer in Bangkok. The film warmly depicts the process of the two reuniting in a foreign country and gradually connecting with each other.
Omoinotake watched the film in advance. They created "Gravity" based on the image of the two characters' relationship—a mutual unrequited love, reuniting in a foreign land as if drawn together by an unseen force. Upon the theme song's announcement, the band commented, "For us, a very important 'love song' has been born."
The two lead actors and the director also released comments about the song. Morisaki stated, "The title 'Gravity' means to be drawn to each other, and I feel this theme song expresses the destiny of these two fateful individuals to shine together again. It's filled with feelings that are both heart-wrenching and full of hope." Mukai said, "This is the first time one of my projects has had a theme song, so I was very happy. After watching the movie, it has a pleasant feeling, as if it gently envelops the entire film, and I thought it would be perfect for listening to on the way home." A trailer featuring a portion of the theme song is now available on YouTube.
It has also been announced that Omoinotake will hold "Omoinotake One Man Live in Taipei & Bangkok" in Taipei in November and in Bangkok in December. Details such as ticket information will be announced at a later date.
Omoinotake Comment
We are Omoinotake, and we had the honor of creating the theme song.
"When and how exactly are connections and destiny born?" This was the first thought that came to mind after we finished watching the film (LOVE SONG).
A person meets about 30,000 people in their lifetime. To meet that one special person you could call "destiny" among them...
...is something so precious that the word "miracle" can't even begin to describe it. Even if they love each other, miss each other, hurt each other, and become separated, they are drawn together as if by an irresistible force. We wrote the song "Gravity" for the "strong gravitational pull of love" between Sota and Kai, which transcends their countries of Japan and Thailand.
For us, a very important "love song" has been born. We are eagerly awaiting the day it reaches your heart in theaters.
Win Morisaki Comment
When I first heard it, I thought it was the perfect song for the film (LOVE SONG). Humanity cannot resist gravity. It's a song that seems to convey the feeling of wanting to defy that gravity to be with the one you love; it truly represents the feelings of Sota and Kai. The title 'Gravity' means to be drawn to each other, and I feel this theme song expresses the destiny of these two fateful individuals to shine together again. It's filled with feelings that are both heart-wrenching and full of hope. Everyone, please listen to it a lot!
Koji Mukai Comment
This is the first time one of my projects has had a theme song, so I was very happy. After watching the movie, it has a pleasant feeling, as if it gently envelops the entire film, and I thought it would be perfect for listening to on the way home. The song, which was written for the film, carefully depicts the relationship between Sota and Kai, and the title "Gravity" also evokes the image of the two being drawn to each other. Words like "destiny" and "sun" are also connected to the movie and are very striking. Is this song from Sota's perspective or Kai's? Please find out in the theater.
Director Champ Weerachit Thongjila Comment
The moment I first heard "Gravity," I was instantly drawn into the world of the song, and my heart was captured in an instant. Even after just one listen, the beautiful melody lingered in my ears and felt like it was resonating throughout my entire body. I was certain that everyone who hears this song will be as deeply moved and touched as I was.
This song is a true gem of a love song that lets you feel the great power of love. It feels like your own racing heartbeat is synchronizing with the music, and it fills you with a sense of happiness that makes you want to listen to it over and over. Every single element that makes up the song is wonderful, and I was moved from the bottom of my heart. Above all, I feel this song perfectly complements the emotions of the characters, making it an indispensable presence that completes the love story in a deeper, more moving way. The addition of this song perfects the world of love that the film depicts.
Thank you so much for delivering such a wonderful and heartfelt song.
