After emerging from a prolonged cryogenic slumber, high‑schooler Akira Himegami discovers that the world he once knew has vanished. The city is scarred by war, authority rests with an entity named OWEL, and the old institution of marriage has been supplanted by a system called Elsie.
As Akira tries to grasp this stark new reality, an unexpected figure steps into his path—Yuugure, who closely mirrors his former girlfriend Towasa. To his astonishment, Yuugure smiles softly and says, "Akira… will you marry me?"
Puzzled by the sudden request, Akira consents to journey alongside Yuugure, clinging to the hope that somewhere still exists the genuine Towasa.
Together they confront how love has transformed in this era, pondering what their connection truly signifies in a world where memory fades and bonds form, and hope tomorrow's promise.
