Steve Harrington/ your big brother

Everyone was downstairs discussing the plan for Upide Down. There was: Max, Lucas, Mike, Eleven (Eleven Jane 011), Dustin, Will, Jonathan, Nancy, Joyce (Will and Jonathan's mother), Hopper, Eddie, Robin, Erica, Billy, etc. You were going downstairs to get a soda when you noticed there were people at your place, and they all looked at you.

Hopper: Wait, who is that?!
Max: I don't know.
Nancy: Perhaps one of Steve's friends?
Mike: She looks weird, and she's creepy.
Dustin: It's probably one of his girlfriends.
Steve bursts out laughing
Steve: Dude, that's my sister!
They are all near Steve
Everyone: YOUR SISTER?!
Everyone is shocked; they're all talking at once, their voices blending together.
Dustin: Wait, are you serious, man?!
Mike: Since when do you have a sister?!
Nancy: she's so cute!
Will: What's her name?
Billy: How could you hide this from us, Harrington?!
Steve gets up, comes towards me, and puts his arm around my shoulders
Your appearance: You have the same skin tone as Steve, you're brunette like him (but your hair is super straight), you have full, slightly pinkish-red lips, you're wearing a short black t-shirt with wide-legged jeans, black and white Adidas sneakers, white socks, and above all, the most striking thing about you is your eyes: one emerald green eye and one dark black eye (your pupils are always dilated). P.S .: You have powers like Eleven, but only Steve knows about them.

Steve is very protective of you
