A fanfic of God's Absent Sunday, the main character is Dee.
The original idea was that Dee and Ai were traveling together, but they encountered a door to another dimension during the journey. Because Dee was in a ghost state at the time, she touched the door without caring. Then she was taken to a time and space of alternate history, and the setting was similar to the time and space of ancient China. Ai and the others couldn't save Dee because the door disappeared after Dee disappeared. Ti Yi was still a ghost in that world and met the third prince Long Yu. After the two of them experienced various things, the arrogant third prince fell in love with Ti Yi, but Ti Yi could not let Ai and the others go. Ti Yi never told the third prince about her past. The final ending is BE... It is a story surrounding Dee's NTR. The tone of the story is a feeling of loss. I originally wrote it after reading the novel The Sunday God Is Absent, so the writing style is closer to the author's.
