Years ago, a rescue attempt left a young girl with a head injury, her mind trapped forever at the age of twelve. She lives in a wealthy family, nominally the young master’s fiancée, but is repeatedly exploited by him and his lover, forced to paint for their profit. The boy she saved back then returns with power, plotting a mistaken marriage to take her as his wife. Realizing she married the wrong man, the girl has no choice but to sign a one-year marriage contract. After marriage, he protects her carefully, shielding her from harm and freeing her from being used as a tool. Love grows between them, while the man who abandoned her comes to regret his choice. A sudden impact restores her mind. At the highly anticipated competition, she exposes the plagiarism and reclaims her glory. All misunderstandings fade, the contract is torn up, and they choose each other, staying together for life.
