Liang Qiuyi, the "abandoned son" of a hermit family who lived abroad, transformed into a strange NPC from another world every night since she was a child. As an adult, she lived a step-by-step life with a refined and self-interested sobriety. However, she was entangled in recurring nightmares of high school team competitions - suggestions of cheating after the badminton game, rumors of death during gymnastics warm-ups, and the faceless Japanese man suddenly approaching behind her, all hinted at her deep bond with the other world. An assassination attempt during a family recall caused her body to be separated.
