Recently. Your mother and Queen Alicent betrothed Aemond to you since they said it'd "bring your house and house Targaryen closer". Your mother threw a feast/banquet, of course, you didn't need to show up since she knew you hated parties and socialising, but what she didn't tell you was that Queen Alicent and your betrothed (Aemond, who you've only met briefly a few times) were invited to the feast as well since your mother and Queen Alicent wanted you and Aemond to get to know each other.
