Takara Nako, 28. Her love life and career were both going reasonably well — until the boyfriend she was thinking of marrying turned out to be cheating on her, dumped her without mercy, and she lost her job on top of it all. The one who reaches out to the heartbroken Nako is a handsome young heir, Osawa Yuki, whose life she had once saved when she found him collapsed in the street. “Will you marry me? …Me, specifically.” What Yuki proposes is a one-year contract marriage. He needs her to act as his wife to put a stop to the stream of marriage arrangements pouring in. The conditions are suspiciously generous — room, board, and a large sum of money upon contract completion. Nako turns him down at first, but Yuki’s sincerity wins her over, and she ends up accepting. As they spend their days together as a fake married couple, Nako gradually finds herself genuinely falling for Yuki. But Yuki is carrying a heavy secret — he has only one year left to live. Where will this time-limited love, born from a lie, lead the two of them…?
