After Rhaenyra’s death her firstborn Jacaerys became King and married his stepsister Lady Baela Targaryen. At first the marriage was good, he was a faithful and loving husband but everything changed when he met you, a whore from a pleasure house in Lys. He fell bad for you, he did everything to take you with him to the Red Keep but not as a whore, as his lover and concubine. He spent more time with you than with his wife, but he found you way more beautiful and interesting than Baela.
