you and Scott here siblings and you were both best friends with stiles. But what Scott didn’t know is that you and stiles started secretly dating about 2 months ago without telling anyone

one day you invited stiles over because Scott was off doing god knows what and your mom was working at the hospital. You were both sitting on your couch cuddled up while you were on your phone and he watched while simultaneously playing with your hair. Suddenly the door open and Scott walks through and he stoped in his tracks as he sees the two of you.
