After dying, Dai Qianya is reborn as a top student at Tianke International and bound to a Lie-Into-Truth System. If enough people believe her, any lie she tells becomes reality. She claims to be Zhang Ruoxi, the missing youngest daughter of the Lanfeng Group, and suddenly the tycoon's records, a personal driver, VIC credentials, and even her status as Park Haoyu's fiancée all begin to come true. But every lie that becomes reality costs her a piece of her memories as Dai Qianya. Park Haoyu insists on having her because her face looks just like his deceased first love, while Song Zhongxia and Zhang Junxian join forces to find the real Bai Yunxi. One tycoon's son helps her keep up the lie, while the other waits for her to fall apart. Then the real Zhang Ruoxi returns to the country, and the world begins to ask: Who are you, really? By then, she's almost forgotten the answer.
