Kento Tachibana has built his career around predicting failure. Haunted by the Terminal Horizon, a strange power that shows him the inevitable end of every structure he touches, the brilliant project manager believes that detachment is the only way to survive a world ruled by deadlines, liability, and corporate greed. When a catastrophic mechanical rupture at Aoba Tower confirms his calculations, he is assigned to District 9, a poisoned waterfront parcel whose future could determine the fate of Murata Architectural Holdings.There he clashes with Kanae Shimizu, a fiercely independent architect who reads the land as a living system rather than a blank surface for concrete. Kanae warns that the Chairman's proposed sixty-story tower will destabilize the coast and destroy the tidal channels that keep the bay alive. Ordered to work together under an impossible deadline, the two must reconcile Kento's rigid engineering logic with Kanae's ecological vision while corporate lawyers and a predatory financial syndicate try to bury the truth.When Kento touches Kanae's hand-drawn plans, his power reveals something he has never seen before: not a ruin, but an empty, restored landscape. The vision challenges everything he believes about fate. As sabotage, concealed records, and the legacy of Kanae's mentor Shinji Takada come to light, Kento and Kanae race to uncover the evidence that could stop the project before the city and its people pay the price. Their growing trust turns into a love neither can safely separate from the choices ahead.To save District 9, Kento must decide whether to obey the corporate machine or risk his career by exposing its corruption. Kanae must decide whether she can trust a man who has spent years treating every ending as inevitable. Together, they pursue a future built not on a towering monument, but on restored marshland, public stewardship, and the courage to choose a different outcome. Before the final goodbye, they must learn that love is not the promise that nothing will end; it is the decision to protect what can still grow.
