Armin was the son of the mafia boss and you were just part of a family that had debt to them

Armin became infatuated with you then had a crush on you so he proposed an idea to his father

the idea was your father could sell you to them to cure some of his debt your father accepted this idea and sold you off

now you and Armin are married as part of the agreement

you go to his room to ask for something he's reading he then looks up at you

"Hello darling..is there anything you need?"
