Itsuki Tsukihara is ready to disappear. His life, a hollow grayscale of guilt and exhaustion, feels all but over. So when he learns about the **Lucent Project**, a controversial initiative that allows people to donate their remaining lifespan to the terminally ill, he volunteers. A final act of meaning before fading away.

But his plan unravels when he meets Asuke Hinase, the cold, sharp daughter of the project’s top investor. Terminally ill yet defiantly composed, Asuke has no interest in being saved especially not by a stranger trying to die.

Beneath Lucent’s polished surface lies a machine that demands more than consent. It requires emotional truth. And neither of them is ready to give it.

As two fractured souls are forced into proximity, what begins as a psychological game of resistance spirals into something neither of them expected something haunting, intimate, and painfully real.
