Two-half twins of the same origin are a magical existence. They were born together from their mother\’s womb and have the same genetic sequence. However, they are two independent individuals with independent thoughts and emotional experiences. I have a twin sister. Although we have similar appearance and body shape, our personalities and hobbies are completely different. When we were children, we liked to wear the same clothes and imitate each other\’s movements and language repeatedly like a mirror, so that others could see us.
