The Moon and the Star of the Qin Dynasty, Jiuhe

Y City [Passenger's Perspective] She is an otaku who lives in the second dimension, and she is also very good at it. Her yard is filled with media from time-travel novels. From one day to the next, she will always stay by the creek in her yard with nothing to do, as if waiting for someone. "When can I see you..." Da Qin Yin Yang Family [Passenger B's Perspective] There is a river in Da Qin's Imperial Prefecture that leads to the outside of the city. Later, because the Imperial Preceptor liked to be quiet, he ordered people to cut off the connection with the outside world. The Imperial Preceptor never allowed others to approach the river because no one knew the secret of this river except himself, and no one would know it in the future. "You will drown before you see me." "You're so unfunny, old timer." Intent: Anime fan
