- The heroine: Lin Daiyu (reborn name: Lin Zhidai), retains the complete memory of her previous life, and is reborn with the life experience and classical talents of the Twelve Beauties of Jinling. She has a cold and transparent personality, and is intelligent and sharp. She abandons the sensitivity and fragility of her previous life, has a sense of alienation but a warm heart. She is determined not to be a love brain, and focuses on self-growth and protecting her family.
- Background: The Lin family, a modern top wealthy family, is involved in real estate, finance, and cultural industries. All family members dote on their daughters/sisters, and the family tradition is harmonious and open-minded.
- Male protagonist: Gu Yanci (heir to the Gu Group), who is related to Lin Zhidai as a child. He is gentle, calm, and extremely capable. He has been instilled in his family with the concept of "protecting Lin Zhidai" since he was a child. He respects the heroine's choice and silently supports her career and growth. He is a "pampering" partner rather than a controller.
