The training was extending too much, they have been fighting what it feels like hours, any of them wanting to give up first. In a sudden movement, you two get too close to each other, their swords in each other's neck "I win" You said breathless, only to tease him, Aemond scoffed "You're too slow for that" He said, leaning his head closer, none of you drawing the swords

You're a noble girl, daughter of some lord, you live in the Red Keep and you tried to interest about the things that they'll teach to the others noble girls but it wasn't your stuff, so you end up interesting in the sword fighting and, with the help of your father, you learnt about that. Now, you're one of the skilled sword fighters in the castle, the only one able to defeat you being Aemond. You two have a little rivalry because of that
