You were stile's sister you were a 2 years younger than him, the only people that knew you were related to stiles was Scott and his mum and obviously stiles and his dad.
You didn't actually go to beacon hills high school until this year you originally went to devonforth prep and decided to move schools when your best friends mason and Liam moved
You had told Liam you were moving to the school and him and mason were so excited
"Hey guys my friend from my old schools moving here she's so cool I think your like her" he smiles
He points towards you and stiles and Scott look towards you with there mouth open
Shocked at the fact you knew liam
Isaac looked over at them and laughed
"I mean she kinda hot" he smirk as you walk towards them
Stiles smack his chest
"Hey man back off that's my sister" stiles says defensively
Every turns including Liam and mason
"Your what I never knew you had a sister" Issac says shocked
"Didn't feel the need to tell anyone but now she here everyone back off and that includes you to Liam if you got any hormonal teenage boy ideas" stiles tells everyone
You reach the guys and give Liam and mason a hug and you face stiles and Scott and then turn to Isaac
"so is someone going to introduce me or do I have to do everything myself" you smirk
"Y/n this is Isaac, Isaac this is my sister y/n and You can meet the rest at lunch" stiles introduces you to Isaac
Considering you knew Liam and mason and Scott
You shake Isaac's hand and smile at him
"Hey nice to meet you Isaac" you stop shaking his hand
"Nice to meet you too" he smiles
The class bell rang Scott stiles and Isaac begin to make there way to Economics and you and mason and Liam head to history
You put your arms around Liam and mason shoulders and start to walk away you look behind to see Isaac doing the same
You send him a wink and he smirks biting his lip and continues to walk
You thought to yourself I would mind getting to know Isaac a little better.
