Human AU it is, in old times. About gender explorations while growing up and developing relationships.
With Lucifer currently Samael being the daughter in a very rich and influential family. Realizing he is a boy after all. Not hating the dresses and long long hair but feeling off when being fretted over like a fragile doll that is meant to stand prettily to be looked at. He likes being delicate, but he hates the demands to be still and obedient. Like Eve, a girl of his age from a much less rich family, who likes standing around, looking nice. But she is sweet and they become friends anyway. (sometimes he can't help but grip scissors tight, allowing himself to cut one strand only)
With Lilith currently Leon a son of relatively rich family. Realizing she is a girl after all. Not hating short hair and stiff clothes but feeling off from the treatment anyway. It's not that she wants to be treated like other girls, she would hate it. She is smart and demands respect. But she is not brash like Adam, a boy of the same age from quite influential rich family, who constantly picks friendly fights with her. She wants to be strong, but graceful. (with the dread she awaits when her family deems her hair long enough to be cut)
At some point their families decided to marry Samael with Adam and Eve with Leon. All four are not happy about it. At some point they realize it would rather be another way around.
Adam realizes he would rather compete with Samael in different ways, when she reveals she would rather run around and create a mess. She is funny. But Eve? Eve is cute and attentive. Adam wants to be able to protect her. And Eve in turn likes how loud and warm Adam is, she feels like a sunflower, turning to everywhere he is. And she would rather be friends with Leon, she likes how he does her hair, how calm and understanding he is with her.
And then Leon and Samael, they feel like kindred souls. They would confide that the world views them wrong, they would share each other's clothes, make a pretend breast for Leon, collect Samael's hair to make it look short. Leon would reveal how glad she is to have more lean body despite what others think. Samael would reveal how glad he is to have small breasts despite what others think. Together they realize they less hate how they look and what they have, and hate more how others decided how and who they have to be because of it. And for continuing pretending for others they hate themselves a little too.
All of them go to a private school. Kids from less rich families can attend too. With connections or smarts.
Like Rosie, whose family isn't that rich, but has enough connections to get anywhere. Like Alastor, whose family isn't rich at all, but he is smart enough to earn himself a place.
Rosie and Alastor are close childhood friends, closer than a family. They both have morbid interests and they share how they have no idea what are these rules that the world came up with, they would rather ignore what they deem useless. Rosie decided she is not a girl, she is a lady. Alastor decided he is not a boy, he is a gentlemen. And they both decided they are the ones who choose what does that mean.
Rosie is considered 'weird' by her peers, but harmless. She doesn't bother to hide her eccentric nature, amusing herself with others reactions. Alastor is viewed as well mannered, but this is a mask he enjoys to perform, tricking others and entertaining himself by elaborate reveals.
Eve thinks they are curious but is she is fearful of them. Adam thinks they are annoying and doesn't want to deal with them.
Samael and Leon can't help but being amazed by them, wanting to know them better.
Their freedom is addicting.
Alastor is witty and sharp, Rosie is brutal and sugary. Samael, now Lucifer cuts his hair and no longer hides his snark and chaotic nature. Leon, now Lilith drowns herself in elegancy and refuses to cut her hair no more.
The four of them leave the town together the second they graduate. Lucifer and Lilith being disowned, Rosie leaving behind a family that tolerated her at best. Alastor's mother that he loved is no longer with him. And Alastor's father whose fault it was... is no longer here too. By shared effort.
The engagements are broken, leaving Adam and Eve as each other's only option. It's what they wanted anyway. But still the puzzlement and confusion was left in place of their departed friends. And maybe hope to reunite some day in the future.
