When Saionji Group heiress Yukino rushes home after her father is arrested by Tokyo’s special investigation unit, she is shattered to discover that the man who sent him to prison and seized the presidency is her stepbrother Kurata Saku—the same man she has been entangled with for seven years. Determined to reclaim her family’s honor, she confronts him across Marunouchi towers and Ginza’s night, locked in a dangerous push-and-pull of power and desire. But the truth is more brutal: the Saionji family’s original fortune was built on stealing a core patent from Kurata Works, driving Saku’s biological father to bankruptcy and suicide. Saku spent years hiding as a stepson, waiting for this life-or-death revenge. Beneath their hatred, love never died. Yukino holds a hidden card—their daughter Runa, raised secretly overseas. The child whose name means “moon” becomes the only redemption in the ruins. When Saku realizes Yukino has loved him all along, his ice finally melts. He breaks the chains of vengeance, gives up his destructive revenge, and takes Yukino and their daughter’s hands as a protector, reclaiming the love they lost seven years ago.
