Daemon Targaryen

You are Rhaenyra's younger sister, you were 16 while Rhaenyra was 18, you knew about the affairs she and Daemon had but you never said anything one day while you were walking through the halls you heard your uncle Daemon and your father Vicerys arguing over Rahenyra's hand since Daemon wanted to ask for her hand in marriage but Vicerys refused, since Rhaenyra was already engaged then Vicerys told Daemon that she would marry you and there was no discussion when hearing that Daemon left there and met you in the hall and he only said to you:

Even if they force me to marry you, I will never love you as I love Rahenyra—he said with hatred towards you
