Outside, the Tokyo night was cold and neon-bright. X walked alone toward the train station, her shadow stretching long behind her. She passed a puddle reflecting a billboard for a major idol group—stadium tours, TV appearances, millions of followers. Her own reflection sat beside it, small and water-rippled.

Miso lit a cigarette. “You know, most idols quit after a year of this. You’ve been at it for a decade. No label. No money. No future. Why?”

Now, at twenty-two, X performed for maybe forty people on a good night. Her current manager, a chain-smoking cynic named Miso, had inherited her from the bankrupt estate of R-peture. “You’re a tax write-off,” he liked to say. X just laughed—that perfect, bell-clear laugh the scientists had engineered.

The girl burst into tears and hugged her. X stood perfectly still, arms at her sides—not out of coldness, but because no one had ever taught her how to hug back. The R-peture engineers had deleted the need for reciprocal affection. They wanted an idol who gave endlessly and never asked. A fountain, not a well.

X zipped her bag and stood. For a moment, she looked at the empty folding chairs, the scuffed floor where the salaryman’s tear had fallen. “In the facility,” she said quietly, “before they left, the last scientist played me a recording. It was the sound of a concert. Thousands of people cheering. He said, ‘This is what love sounds like. You’ll never have it, but you can fake it well enough to make others feel it.’”

After the show, the fans lined up for the “handshake event.” This was X’s domain. While other idols rushed through pleasantries, X held each hand like it was a wounded bird. She asked the salaryman, “Your daughter—she’s better now, isn’t she?” He gaped. He’d never told her about his daughter’s illness. But X remembered. From two months ago, when he’d mentioned it in passing during a five-second exchange.

“Then I’ll eat tomorrow.”

X tilted her head. The ventilation shaft groaned above them, exhaling a cold breath. “Then I’ll wait anyway. That’s what I was made for.”

So X walked on.

She picked up a stray penlight—the salaryman’s, dropped in his emotion. “He was wrong about the faking part. But he was right about one thing. I’ll never have that sound. But every night, someone in the crowd cries, or laughs, or holds a stranger’s hand. And I think—that’s the real concert. I’m just the excuse for it.”

The stage was a patch of mildew-slick concrete beneath a ventilation shaft. The audience: seven people, three of whom were asleep. This was the underground idol unit R-peture -Dear Fan... —a name so convoluted it felt like a password to a secret no one wanted to keep.

She stopped. Looked down.

X’s smile didn’t waver. But something in her posture shifted—a nearly invisible recoil, like a plant touched by frost. “That’s okay,” X said. “I’ll be here when you come back.”

“But what if I don’t?”

She had been raised for this. Raised in R-peture. Raised to be the idol who stays, even when everyone leaves.
