In her previous life, Gu Jinnan fell in love with someone she shouldn't have loved, causing her whole Gu family to be wiped out. On her wedding day, she took poison and personally killed the person who had made her feel cold.
After her rebirth, she only wanted to take revenge and protect the Gu family's stability for hundreds of years. She investigated the family thieves internally and a series of people related to the frame-up of her Gu family externally. She wanted to make them all pay the price they deserve.
Different from her previous life, she made her own decision to marry the prince who was rumored to be a philanderer. She saw through the prince's hidden clumsiness for many years. In order to win over the prince and show her sincerity, she and the prince talked about cooperation. The two used each other and worked together.
Seeing the man from his previous life again, Gu Jinnan endured the pain and smiled. He was still approaching her in every possible way, just like in his previous life. She pretended to be friendly just to seek revenge.
