Orphaned at sixteen, Bian Yue inherits her family's vast wealth, becoming Xiangjiang's most coveted heiress. The Li family welcomes her into their fold, where she meets Li Siheng—a man whose gentle approach through rows of bodyguards steals her heart instantly. Six years later, their marriage crumbles when Li Siheng admits his feelings have shifted, leaving Bian Yue determined to end things with dignity. As scandal surrounds Shen Jin, the ruthless Shen family patriarch battling terminal illness, whispers of karmic retribution fill Xiangjiang's streets. Seizing the moment during a torrential downpour, Bian Yue arrives at his residence soaked and drenched, proposing an unconventional union. His cold acceptance shocks the city, their hasty marriage igniting widespread uproar and speculation. When Li Siheng encounters Bian Yue again after the wedding, desperation overtakes him—he abandons his car to reach her in the rain, clutching her hands and begging for freedom so he might finally claim her. That same night, Shen Jin cuts short his overseas trip upon learning of the encounter, returning to confront his wife at home. Silhouetted against the darkness, cigarette in hand, he pulls her close and kisses her with fierce intensity. He vows the harbour city's rainy season will pass, just as he will remain, waiting faithfully for her to come back to him.
