Lin Wangshu was the daughter of a mistress. After her mother stabbed her biological father to death, she planned to jump off a building with Lin Wangshu and end their lives. Lin Wangshu was reborn. After being reborn, she was unexpectedly adopted by her father’s wife. Her adoptive mother sent her to school and taught her to paint, treating her even better than her biological mother had. But everyone else called Lin Wangshu stupid because she was bad at school and slow on the uptake. Only one person thought she was wonderful: Gu Qingshan. Like Lin Wangshu’s knight, Gu Qingshan always appeared to protect her when she was in danger. In truth, though, he was the one who needed protecting more. As they grew close, they saved and protected each other. In the end, the two lovers found their way to each other.
