Singaporean-Chinese jewelry designer Su Wan faces ruin when her studio is framed for plagiarism, and her father requires urgent, costly surgery. Desperate, she crashes a private gala hosted by Li Jin, CEO of multinational Obsidian Capital, to beg for help. The British-Chinese tycoon, beset by family marriage pressures and an assassination attempt by business rivals, is saved by Su Wan’s quick thinking—and he proposes a one-year "contract marriage" to solve both their predicaments. Initially clashing over their contrasting personalities, the pair gradually grows closer while cohabiting. Rejecting the role of a trophy wife, Su Wan joins Obsidian’s subsidiary Starry Gems as a designer. Despite repeated sabotage by Li Jin’s childhood friend Lin Weiwei, she rises through the ranks, wowing the industry with designs blending Southeast Asian cultural elements. Meanwhile, Li Jin quietly clears obstacles for her, and they stand side by side amid corporate battles—fending off attacks from the Rothschild family branch, thwarting his uncle Li Kun’s power grab, and confronting Southeast Asian gang threats. From Singapore to London and Bangkok, they weather workplace intrigue, family feuds, cross-border conspiracies, and life-or-death trials. Their contract marriage blossoms into genuine love. Su Wan evolves into an internationally acclaimed designer, while Li Jin secures full control of his business empire. After ing Li Kun’s final gang-backed plot, they hold a grand wedding and welcome a new life, achieving both career triumph and romantic fulfillment—a legendary love story transcending cultures and classes.
