Ae! group’s New Song “Destiny”: Musashino Rondo Theme Song

It has been officially announced that Ae! group will perform the theme song “Destiny” for the upcoming TV Asahi Saturday night drama “Musashino Rondo”, starring member Masakado Yoshinori.


The new song “Destiny” by Ae! group is a deeply emotional love ballad with raw, straightforward lyrics that express the frustrating, aching feelings of a love that feels so close, yet out of reach—unable to be conveyed despite the desire to do so. With its poignant tone, the song perfectly captures the world of the drama and enhances its emotional resonance.

Additionally, a special promo video featuring both the main drama footage and a first preview of the theme song will be released today at 6:00 PM JST on the official YouTube channel. This sneak peek offers fans an early glimpse into the heartfelt world of “Musashino Rondo” ahead of its premiere.

Comment from Yoshinori Masakado

It’s another dream come true—to have my group perform the theme song for a drama I star in!
This song is a heartfelt rock ballad that expresses the passionate emotions of a clumsy love that doesn’t go as planned.
It’s very much in the style of Ae! group, and at the same time, it perfectly deepens the emotional image of
Musashino Rondo.
I truly believe it’s the perfect match for the drama. Please enjoy it together with the story!


The drama is a live-action adaptation of the popular manga by Hiroshi Kawauchi. Masakado will take on his first romance drama role, portraying a protagonist who has harbored unrequited love for a woman 10 years his senior. Actress Takanashi Rin has been cast as the heroine.

The story follows a young man who has been in love with his neighbor—an older woman—since childhood. However, no matter how much time passes, she continues to see him as nothing more than a “little brother” and a part of her family. Just when he begins to give up hope, a romantic rival appears, reigniting his determination. He finally gathers the courage to make a bold move, setting off a dramatic shift in their long-standing relationship. After 10 years, his unrequited love finally starts to take a turn.

While the drama depicts a pure love story, it is packed with heart-fluttering moments, including hugs and kisses, as well as a love triangle that will keep viewers on edge. With unexpected twists and turns, Musashino Rondo promises to be a mature, emotionally charged romance.

Masakado plays Ryuhei Agawa (25), the son of a soba shop owner, who has been devotedly in love with his neighbor, Tamaki Musashihara, since childhood. Ryuhei is reserved and rarely expresses his emotions, but during his middle and high school years, he confessed his feelings twice—only to be met with rejection. To Tamaki, he was nothing more than “the boy next door”, and their relationship remained unchanged for 10 years. Though he dated other women during that time, they always saw through him—realizing his heart was never truly with them—and the relationships ended in failure.

Tamaki, the woman Ryuhei has long been in love with, is a ballet instructor who teaches at her home studio. She has a straightforward, no-nonsense personality and tends to act dominant around her younger brother. However, she also has a soft spot for falling in love easily. Despite Ryuhei’s unwavering affection, she never took his words seriously, brushing them off as “childish nonsense” since she had known him since infancy. But everything changes when she falls head over heels for one of Ryuhei’s colleagues—her ideal type. As she struggles with her growing attraction to this new man, Ryuhei suddenly begins aggressively pursuing her, making her see him in a new light for the first time.

The drama will explore their longstanding yet complicated relationship, a love triangle, and the emotional journey of realizing love that had been right beside them all along.
