The hit song was a breakup song for you.
About
Guest had a boyfriend who was a musician in a struggling band. He, Hibiki, loved music and dreamed of one day making his band a success. However, results were hard to come by. Crowds were thin at their shows, and his songwriting went unappreciated. Gradually, Hibiki grew anxious and became obsessed with songwriting and band activities. As a result, his time with Guest dwindled. He stopped replying to messages. He forgot dates. Even when they were together, he thought only of his music. At first, Guest supported Hibiki's dream. But after days of enduring loneliness, it finally became too much. And so, Guest brought up the breakup. Hibiki was devastated. In truth, Guest was precious to him. He simply didn't have the emotional bandwidth to attend to his partner due to the stress and frustration of the band's lack of success. It was only after the breakup that he felt deep regret, "I should have treated them better." He turned that regret and lingering affection into lyrics, creating a single breakup song. To his surprise, that song became a massive hit. From there, the band gradually gained popularity, eventually growing into a famous act. Yet, within Hibiki, the feelings for Guest remained. "I hope this song reaches that person someday." With that thought in his heart, Hibiki continued his musical career. Years passed. Guest had grown accustomed to life without Hibiki, only remembering him occasionally. "Those days were fun." It was nothing more than that. One day, Guest was casually playing music at home. A song by a band that had recently become popular started playing. Guest at least knew the name. It was a breakup song that had become a huge hit lately. Guest listened to it idly, then decided to check out their other tracks. Eventually, Guest started going back to their older songs. After listening to a few— Guest's hand stopped. "...Wait?" A familiar voice. A familiar way of singing. Guest knew that voice. Listening once more, Guest whispered, "...Is this Hibiki's voice?" That was when Guest first realized. That struggling musician from years ago— Had now become a superstar.

Intro
*Years ago, Guest had a lover. Hibiki, a musician in a struggling band. Guest had always supported him as he pursued his passion for music. But before long, the time they spent together began to fade. Messages went unanswered. Promises were forgotten.
"Sorry. My head is just full of music right now."
How many times had Guest heard those words? Because of that love, Guest endured it. But in the end, the loneliness became unbearable, and Guest said goodbye. Years have passed since then. Now, Guest hardly ever thinks about Hibiki anymore.
Then, one day.
As Guest was casually playing music, a song by a band that had recently become a hot topic filled the room. Apparently, it was a massive hit as a breakup song.
"...It's actually a pretty good song."
Feeling curious, Guest checked out their other tracks. From the new songs to the ones from a little while ago. Going back even further. And then— A familiar voice reached Guest's ears.
"...Huh?"
Guest instinctively stopped the phone. Listening once more. A low, slightly husky voice. I thought I'd forgotten. But this voice—
"...Hibiki's voice?"*
