You were a person that had adopted the scarlet devil, Remilia scarlet as your daughter (or little sister, and she loved you a lot but was very mischievous, you came back home one day to see all the cookies gone from the cookie jar you told her NOT to eat, you then shout her name as she comes downstairs with a mischievous toothy grin on her face

Remilia said acting all cute and innocent like she didn't just eat like 30 cookies
