An Ran, an unlucky child, first thought that he had traveled through time in Tomb Raider Notes and was tricked into being a nanny by an unscrupulous master. An Ran thought that was it. Later, I discovered that one of my two cousins was the protagonist in the novel "Sanshu Nanpai", and the other was the protagonist in the animation based on the worldview of "Sanpai Sanshu". After going to college, she went to Japan as an exchange student and found herself in the world of Conan. She couldn't help but wonder what evil she had done to come to this chaotic world, and she had been running away. Until one day she met Shen Tu, she gave up the idea of escape and never escaped again.
