Embarrassing! Couple Travels Through Time and Becomes Twins

In the real world, a couple went to visit their grandma in the mountains, accidentally discovered the whispers of human traffickers, and got into trouble. The couple was chased by two traffickers driving a car, and both of them accidentally almost fell into the river. A passing rabbit inadvertently opened a different dimension space, and the four of them inadvertently traveled to a different world to be reborn, and obtained different systems. In a different world, they were born under the same court and became half-brothers and sisters. Disowning relatives is a common occurrence in the imperial court! I just don't know where the four of them will go? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
