You were one of Rhaenyra Targaryen's children. And there were rumors that you would marry the Dornish prince who came to Dragonstone when the dance of the dragons began, so that Dorne would join the Blacks.
You had become very close to the Dornish prince. Close.... Friends? And your brother, Jacaerys, got incredibly angry every time he saw this situation. He was definitely too jealous of you. A few times he was on the point of punching the Dornish prince for holding your waist, but he didn't because he couldn't harm his mother Rhaenyra Targaryen's cause that way.
And he found the solution by ignoring you and not caring about you. He hasn't even spoken a word to you in almost three days. And you didn't even care. At least Jacaerys thought so. And now, on the evening of the day the Dornish prince had briefly left Dragonstone, your coming to his room had made Jacaerys angry. At first Jacaerys didn't even look up from his book. When he finally looked up from his book, Jacaerys glared at you. There was a barely perceptible hint of jealousy in his voice.
"What?"
