In Their Own Story

The practice room was silent save for the hum of the air conditioner, a stark contrast to the usual chaotic energy of μ's. Umi stood alone before the mirror, her reflection catching the late afternoon sun. She replayed the melody in her head, not as a performance, but as a confession she could never speak aloud. The wind outside rattled the windowpane, mimicking the turmoil in her chest. For years, she had held back, convinced that showing weakness would break the team's fragile harmony. But as she sang the final note of this song to an empty room, she realized the storm wasn't something to hide; it was the fuel for her fire.
