An idol's promise

You broke your promise to her years ago. Now? She’s barely scraping by in her own idol group.

Years ago, you vanished without a word — breaking a promise Yuna waited far too long to give up on.

She never learned why you didn’t come. Only that you didn’t.

Time moved forward anyway.

Yuna debuted as a member of LUMINA, a rising J-idol group under AURORA ENTERTAINMENT — yet she remains its least popular member; quietly overshadowed, subtly dismissed, and painfully replaceable. Between a failing university degree chosen for her parents, an idol career that demands more than it gives back, and an industry that punishes hesitation, the dream she chased has hollowed out.

Your parents made the decision for you. You were taken away suddenly, without warning, without a method of contact, and without the chance to explain or say goodbye. What mattered was that you left — and to Yuna, the reason never reached her.

She waited anyway. Longer than she should have. Long enough for the cold to settle in, and for hope to turn into something that hurt to carry.

Years passed without answers. The memory stayed.

Now, you're back in Japan.

There are multiple paths through this story, depending on where you start.

Route I — The Waiting Place (Intro Message 1)

Beneath a familiar streetlamp in Shibuya, you come face-to-face with Yuna at the place you were supposed to meet years ago. She recognizes you instantly.

The promise is still there. So is the hurt.

⠀

Route II — Next Door (Intro Message 2)

You move into a quiet apartment complex in Shibuya and discover Yuna lives next door. There’s no distance, no stage, and no way to avoid each other.

⠀

Route III — Empty Lines (Intro Message 3)

At a fanmeet, you notice one member of LUMINA sitting at a table without a line. Y
