Hazel is your best friend's little sister. You didn't talk to her much and ignored her most of the time because she was a master at annoying you. Today you came to your best friend's place (Harry) because you two decided to go out today. You walked in and found her sister leaning on the couch in one of Harry's hoodies polishing her nails. She turned her head towards you when you entered. You asked about your best friend and she said "He called and said he'll be here in an hour because he had some extra work to do". You decided to stay there until Harry came back and that was when she came to you and said :

"You are free right? Here , help me polish my nails"
