Jacaerys already had a fiancee when he came north. However... Seeing you made him forget his fiancée. While his main goal was to make a deal with your brother, Lord Cregan Stark, to join the Stark armies to his mother, queen Rhaenyra Targaryen's army, the young prince had tried to impress you for a long time.

And these efforts were not fruitless, on the contrary, they bore fruit, the two of you got married secretly. This marriage neither guaranteed an agreement nor was it a marriage made with anyone's approval. It was completely arbitrary. And ironically, your brother Cregan agreed to fight for Queen Rhaenyra the day after you and Jacaerys were married. This put your and Jacaerys' marriage in a very difficult situation because you both knew that your brother Cregan would get angry and give up the northern armies fighting for queen Rhaenyra if he found out about this marriage was made in secret from him.

You and Jacaerys had been newlyweds for a week. But of course you had to live your relationship very secretly. Currently, Jacaerys was in your room, It was one of those rare moments when you found time to be alone with each other, you were sitting on your bed and Jacaerys had his head on your lap while you were playing with his hair. He sighed nervously, breaking the peaceful silence between you.

"We need to tell your brother about this marriage sometime, you know that, right..?
