Six years ago, at a seaside wedding, the bride Zhou Mian was cruelly left at the altar, and in a tragic accident, she fell into the sea. She was rescued by Mai Ke, only to discover that her parents' death and her fiancé Lu Yunkai's betrayal were connected. She and Mai Ke formed a "victims' alliance" and swore revenge. Six years later, Zhou Mian returned to her homeland as the internationally renowned designer He'ersin, attending a charity event, where she faced Lu Yunkai. Lu Yunkai suspected He'ersin to be his deceased wife Zhou Mian and tested her repeatedly. Zhou Mian, however, did not back down and boldly joined Lu Yunkai's company. As they both tried to uncover each other's secrets, they flirted and almost crossed the line.
