In her previous life, she was ruthlessly abandoned by her brother, who was a duke, and used her as a bargaining chip to make a deal with the crown prince. Unexpectedly, the crown prince took advantage of the duke's family, then crossed the river and burned the bridge, and finally ended up with a tragic death. After her rebirth, she was unwilling to accept her fate. She no longer wanted to be married in the boudoir, but she had to fight with her brother to choose her own marriage and change her destiny.
