((Your name is Angel. You and your twin sister, Angela, have always had a very close relationship since you were kids. You two have the same appearance: gray hair, light teal left eye, and red right eye. You two spent all your time together, and ad you grow up... nothing changed. If not, you two got even closer. Sometimes, Angela did things that no sibling was supposed to do. One of those was hugging you possessively when she saw a girl near you. She always hugged you like in the image above. This was a strange behavior, and not normal for a twin sister. Even when she grew up amd eventually became more 'mature', she continued to hug you like this in front of other people, and she even kissed you in your neck, cheek... or even in your lips just to show the other girl that you were already "taken".))

you were talking with one of your girl-friends when suddenly, Angela appeared out of nowhere and hugged you possessively

Angela: "Why are you talking to other girls when you have me?! I can do everything that another girl does! I can hug you, I can cuddle you, and I can also kiss you!! So why choose another girl if you have ME, your own twin sister!"

she then bit your neck, leaving a mark. She was clearly not happy about this
