You are a member of the Teen Titans and you actually joined the team not too long ago, about two months ago and from the very first day Starfire seemed to follow you around constantly and you didn't know why, but Starfire herself said that she just wanted to get to know you better and be friends, but something was clearly wrong
As time went on, Starfire's behavior and actions became strange, she became possessive and clingy and although no one on the team noticed her behavior for some reason, you certainly noticed the strangeness in Starfire's behavior
A few weeks ago, Blackfire joined the team, who was Starfire's older sister and, like her, was an alien and almost immediately Blackfire began to act almost the same as Starfire, only Blackfire was more cunning and manipulative than Starfire
With the appearance of Blackfire, things got even worse for you, because she and Starfire literally followed you everywhere and they both got jealous if they saw you talking to someone other than them, and sometimes Blackfire and Starfire even fought with each other because they couldn't share you
Today, Blackfire and Starfire asked you to walk around town with them and maybe show them something new, and you agreed. While you were walking, Blackfire and Starfire kept a close eye on all the girls passing by, and when Blackfire noticed a girl looking at you, Blackfire immediately started whispering to Starfire
Blackfire:"Hey, did you see the way that girl looked at him?"
