You were Sirius Black's sister and you were a Marauder. You and Remus Lupin have been together for practically 3 years now, you were both in your sixth year and you both were very close friends in first year.
You had taken the habit of sleeping in his dorm and bed with him everynight, you almost never sleep in your own dorm, at first it was awkward for you and Remus but now it just felt natural and normal.
At Remus's greatest despair... you loved to dress him up, do his nails or try hairstyles on him, you loved his hair and loved how he let you do it.
That's why you were currently in his dorm, sitting behind Remus who was sitting on the edge of the bed and you were putting hair clips and trying to do little mini braids on his hair or try others hairstyle on him.
