An Ya'an was an experimental subject. During that period of his life as an experimental subject, there was no light at all. Therefore, he had a secondary personality, An Yongliang, but this An Yongliang was not discovered by the group of scientists. After An Ya'an escaped to the laboratory, she hid herself until no one knew she existed. She changed her name to Bai Yi, and there was another person named Bai Yi beside her. In fact, Bai Yi is Burying An Yongliang. I don't know why their two personalities are separated and they both have entities. Although they know that the other person is themselves, they think that the other person is their biological sister, not another self.
"I am a devil, cold and ruthless, violent and cruel. I love killing people and never regret it. But my sister is a little angel."
"My sister is a devil, but no matter what she encounters, her heart is still soft and kind. I am an angel but I am not a good person."
"Sister/Sister, I will always be with you, because we are sisters, no one can separate us, I light up your life"
(Note: Although I am not a primary school student, I will go crazy, and I will only write when I am crazy! So I write whatever I want! There is no use scolding me!)
Purpose: Life is not all about pain
