your james potters little sister, you got put in Slytherin, james and all of his friends including sirius are gryffindors

You always snuck into the gryffindor common room to hang out with your brother and his friends, it got to the point where you and sirius developed feelings for eachother, he would always stare at you when you would hang out with sirius and your brother

You both started sharing small makeout sessions with eachother, your sitting in your dorm room when a dog walks into it, you not knowing sirius was an Animagus got scared and tried to get out of your room but sirius/the dog kept rubbing against your leg
