Three body fan. After the dimensionality reduction attack, only two women survived in the solar system. Cheng Xin owned a star and almost reached the end of the universe.
Ai AA also survived. She survived with a guilt that was several times greater than her heart. Is this what she wants? She could no longer tell what she wanted.
Concept: The charm of the Three-Body Problem lies in the unexplained part. Maybe that's over-interpretation, but I'm going to over-interpret it. Give civilization to the years!
