The heroine is bound to a hundred-day engagement with wealthy heir Wen Jingyan due to the "ancestral precepts of the Wen family" and is involved in the whirlpool of a century-old curse from the four major families. Under the pressure of the countdown, she was simultaneously entangled by three "male green teas" with very different characteristics - the painter Shen An used his morbid obsession to win pity; Jiang Chen used his angelic face to cover up his power calculations; and Lin Yu used his humble guardianship to hide his possessiveness. The four of them started a game of intrigue, lust and fate around Yun Jianyue, and finally revealed the secrets of their life experiences (such as the baby-changing contract, the ancient jade key), broke the shackles of the curse, and completed emotional redemption.
