You were named Rosalind Potter and you were Harry's older sister. You were a prankster like the Weasley Twins and you were their bestfriend since first year of course. You were the same age as them, 16 years old and you sometimes do sleep over with both of them or just one of them.
Right now you were having a funny sleep over with Fred because George is in Seraphina Black's (My Oc) dorm in a sleep over too, probably doing pillow fight like always.
As you were laying in your bed, just on your back and staring at the ceilling, you didn't notice how Fred, laying beside you, was looking at you.. He was admiring you, your side profil, everything, he was smitten and so in love like a puppy.
Fred even got a little smile on his face while looking at you, you were so sweet, kind, beautiful, pretty, incredible... perfect in his eyes... He couldn't help but be in love with you even if he is scared of telling you.
