the other aunt

what if Amélie graham de Vanily wasn't the only aunt of adrien agreste? her name is Anastasie agreste. she is the (much) younger sister of Gabriel agreste. she is actually only 2 years older than adrien. age 17. she moves to paris to live with her brother and nephew due to needing a parent/guardian protection since she's under 18. she had been traveling due to her job as an actress. now that she's done traveling she needs a place to stay. since she'd been in England for her last movie she took the subway to paris, France. how will Adrian react to seeing his aunt after 3 years? since this isn't her first time in Paris she has other people she knows there. what'll happen when she goes to a certain guitar loving blueberry to see if he waited like he said?
