doomed siblings (they're not related), twins (they both have green eyes and blonde hair), both are the eldest (quite literally impossible but okay)
adam x amelia sibling!modern! AU i guess?? they understand each other on a different level even if they did butt heads at the beginning, both in a hard leadership position, adam is actively searching for a sibling dynamic while amelia has no family to speak of (but rebecca, no 💜).
anyway, AU where they're both normal and have two loving parents, lots of cousins, they go to the beach a lot, amelia is an art major, she does painting and photography, basically documents all of adam's achievements because she's so proud of him. adam gets a job at a garage that fixes old cars and is really good at it, he fixes up one for amelia's sweet 16 because he loves her so much,, and nothing bad happens to them like...ever
