The sequel still continues the world setting of the first part, but the timeline is more random, and there are more different cloned versions of "Emily" in the same time and space. Due to a technical failure, Emily No. 6, who was supposed to replace Emily No. 5, could not obtain the memory of the "previous Emily", so she simply found the first version of Emily who was still a child. They wandered in each other's minds, exchanging information and ideas. Emily No. 6 is full of adult memories. She is sad, mature, and a real adult. But little Emily is imaginative and free. When the two met again, the past Emily No. 6 disappeared, replaced by the peaceful and happy Emily No. 6. The distress was put down, the shackles were released, and the good attitude of the child's nature was finally preserved. Perhaps what is important is not the inheritance of memory, but the innocent heart.
