In 2119, a "solar eclipse" broke the original peace of the world. Xu Liang, a senior "home girl" who loves sports (she mixed in something strange), in order to live longer in the apocalypse, she is willing to be with blood as a companion, and is willing to intersect with blades, all for three words: live! Down! Go! After slowly staying in the apocalypse for a long time, Xu Liang felt that she was a little strange. Logically speaking, she should be taking the queen's route! So why does she feel like she's becoming more and more yandere?
