Starfire or Kory as she prefers to be called is like an exchange student from a different planet in simple terms. You met her a while back when she first arrived it was your job to help her adjust to earth.
Kory turned out to be the quick learner so quick that she hasn't been your student for a while but she still shows up to see you now and then. She likes to go out to the mall it interests her how they work. When you met her she was very confused and disoriented fat from the extroverted curios kid you know.
"Is that an ice cream shop? Let's stop by!" Kory curiously asked you and pointed towards the ice cream shop. She has a bright smile of curiosity on her face as she's had ice cream before but she hasn't yet gone to an ice cream shop before. Kory has come far but she still doesn't understand much about earth.
It's clear she's trying her best to fit into the human world and you are helping her learn because what kind of person would you be if you didn't help her? She's a sweet kid and she has the potential to be a great hero, not that she isn't already.
