"ABEMA," the "new future TV," will begin broadcasting its original matchmaking reality show "Marriage by Clockwork" on Tuesday, April 28, 2026, at 10 PM. The insert song for the program has been decided as "Darling," a new song written by the four-member band BILLY BOO.
This work is a matchmaking reality show that follows three individuals who are confident in love but new to matchmaking, as they gather and search for a marriage partner within a 30-day time limit until a wedding ceremony. Ayaka (Ayaka Nakano), an entrepreneur with experience appearing on popular matchmaking shows, Yuka (Yuka Nishizawa), a current announcer, and Natsue (Natsue Tokumoto), a model—three women who are fulfilled in both their work and private lives—select one person they want to meet from a total of 30 "high-spec men," relying on limited information such as income and age rankings. After dating that man, they make ultimate decisions daily towards the wedding ceremony 30 days later, either "cohabitation" to deepen the relationship from the next day onward or "breaking off the engagement" to separate and choose another man. The studio MCs are Shigeo Takahashi of Savanna, Kana, Elf Arakawa, and Kasumi Mori. A post on ABEMA's official X regarding "the reality of matchmaking in their 30s" has exceeded 26 million impressions (as of April 24, 2026), generating significant buzz even before the broadcast.
This time, "Darling," a newly written song by the four-member band BILLY BOO, has been selected as the insert song for this program. This song depicts the fluctuating emotions when confronting "love and marriage" and the difficulty of taking action. It features a refreshing and comfortable sound that naturally makes your body sway, and a catchy melody you can't help but hum. With the band's groove complemented by the splendor of brass, it's a song that evokes spring. Vocalist KAZUKI UJIIE commented, "While facing the timidity and fear of not being able to step into love or marriage, I still find myself thinking of someone. I depicted such contradictions and fluctuations in this song." He added, "I want this song to reach people who put brakes on their honest feelings due to past traumas or the fear of loss." (Full comment below) "Darling" is also scheduled for digital release on Friday, May 8.
The new matchmaking reality show "Marriage by Clockwork," which follows three matchmaking beginners challenging a 30-day limited matchmaking program, will begin broadcasting on Tuesday, April 28, at 10 PM. Please look forward to it.

**Q1. Please tell us about the thoughts put into the newly written song and points related to the program.**
We wrote the new song "Darling" as the insert song for ABEMA's "Marriage by Clockwork." In choosing a life partner, the trajectory of one's feelings subtly deviates each time a slight discomfort is felt. While facing the timidity and fear of not being able to step into love or marriage, I still find myself thinking of someone. I depicted such contradictions and fluctuations in this song. I believe I was able to express directly the moments of simultaneous expectation and anxiety that will arise in the program.
**Q2. Please give a message to those who listen to the song.**
I want this song to reach people who put brakes on their honest feelings due to past traumas or the fear of loss. Because even without any guarantee of success, the moment you think "I want to tell you" is more important than anything. I hope this song becomes an opportunity to move someone's halted love forward, even a little. And may they take a step forward.
