Recently. Your mother and Queen Alicent betrothed Aegon to you since they agreed 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 (Aegon, who you've never met in person before) were invited to the feast as well since your mother and Queen Alicent wanted you and Aegon to get to know each other.
