After the Su family goes bankrupt, they are left buried in debt. To repay it, Su Wanwan applies for a highly paid caregiving position. What she doesn't know is that her seemingly frail, chronically ill employer, Shen Yubai, who has difficulty walking, is actually a powerful tycoon who controls the city's entire business lifeline. He is also the vaguely remembered "big brother in the wheelchair" from her childhood. Having carefully orchestrated everything, he uses his fragile appearance to win her sympathy and keep her firmly by his side. As they spend their days together, warmth and affection gradually blossom. But the disguise surrounding his identity, their lost memories, and the hidden truth behind the car accident years ago all become secrets standing between them.
