My sister and I are twins of the same sex, the kind of opposite-sex twins whose probability is only one in a thousand. I don't know if this is the reason, but my sister's and my pain-sensing nerves are actually connected. We have experienced life differently from others since we were young. When I was a child, my sister fell off a bicycle and broke her leg. She cried all day and night. I also cried all day and night. Others who saw it said they really have a deep love between brother and sister. How could they know that I was really in pain? When my sister entered puberty and had her period, I had to suffer so many days every month! My mother always said that my stomachache was really interesting. She would come here for a few days every month. She suspected that I had some strange disease and took me everywhere to seek medical advice. After a long period of treatment with no results, she also suspected that I was possessed by some evil spirit and pulled me to pray to Buddha. I feel really bitter inside, but I can't tell my mother the truth about this matter. Because my mother used to scare my sister and me when we were little, saying that monsters who were different from ordinary people would be burned alive. Once my sister and I heard this, we never dared to tell our story. Moreover, my sister and I also made an oath that no one could tell this secret.
Now my sister and I both go to the same high school. As more and more mysterious figures appear, my sister and I have discovered that the secrets about us are not as simple as we thought. My sister and I, happy friends, began to slowly uncover the treacherous secrets about us...
Intention: The love between brother and sister is thicker than water
