Cannon Fodder Brother and Sister Save Themselves Daily

The eldest prince of the Li Kingdom and the beloved princess of the emperor were obviously the proud sons and daughters of heaven, but they kept seeking death after meeting the male and female protagonists. After rebirth, the brother and sister vowed to stay away from the male and female protagonists in this life and live well. Neither brother nor sister knew that each other was reborn. They disrupted each other's plans many times, and finally couldn't help but want to curse, but when they turned around, the real owner was right in front of them. (This is mainly from the perspective of the female protagonist, not 1V1, there is no male protagonist, please enter with caution if you mind)
