With a single contract, Su Wan married Lu Tingxiao, a business tycoon, becoming the envy of everyone as Mrs. Lu, but also a pawn he used to fend off his family's pressure to marry.
After the wedding, she kept her talents under wraps and played the part of a gentle, proper contract wife. She accompanied him to banquets and helped him deal with open and covert attacks. But as they spent more time together, she fell for the man who was cold on the outside but warm within. Everyone saw President Lu as aloof and indifferent, yet he stood up for her when she was given a hard time, tenderly cared for her when she fell ill, and quietly watched over her when she felt lost.
When his childhood friend Lin Weiwei returned with a grudge and his cousin Lin Zhentao laid a commercial trap, trouble followed one wave after another. Lu Tingxiao sheltered her beneath his wings, only to realize that their contract marriage had long since strayed from its planned course. He thought he had everything under control, unaware that his cold heart had already been melted by her warmth and resilience.
From a contract to true love, from distance to devotion, can they face crisis after crisis and a tide of passion together, turning a marriage that began as an obligation into a lifelong promise of unwavering love?
