How old is Arya in the story?

Arya's story could end in a number of ways. Maybe she'll become a hero and be remembered for her deeds. Or perhaps she'll have to make a difficult choice that shapes her future. Who knows for sure?

To develop the story further, you can introduce conflicts related to the pregnancy. For instance, Arya's physical condition might limit her ability to fight or travel as she used to. This can create tension as she tries to overcome these limitations while still protecting herself and her unborn child.

Arya's character could become more confident and self - assured. After killing the Night King, she might see herself as a true hero and a force to be reckoned with. This new - found confidence could change the way she interacts with others, making her more assertive in her opinions and actions.

Arya and Tywin could also interact in a more unexpected way. Maybe in a situation where they are forced to work together for a short time due to some external threat. During this time, Arya has to constantly remind herself of her ultimate goal of revenge while Tywin is constantly on guard against her, yet also seeing potential in her skills for his own purposes.

Maybe it could be a kind - hearted guy named Leo. He is an artist who is always looking for inspiration. When he meets Arya, he finds that she is his muse. Their relationship starts as he tries to capture her essence in his art and slowly they fall in love.

Arya's character could develop by facing new moral dilemmas. Being in a brothel, she'd see the exploitation of women and might decide to take action against it. This would add a new layer to her sense of justice.

In these stories, Arya's character development is quite complex. At first, she might be in shock and denial about the pregnancy and its implications on inheritance. But as time goes on, she starts to grow into a more nurturing figure. Her skills as a fighter and survivor now get redirected towards protecting her unborn child's right to inheritance. She may also learn to trust others more, as she can't face all the challenges related to inheritance and pregnancy alone.

Their relationship might become stronger. They've both been through so much alone, and now they'll depend on each other more. They could become like partners in crime again, just like when they were kids, but with a more mature bond.

As I don't know the specific arya and sayyeshaa, I can't say how their love story began. It could have started with a chance encounter, like meeting at a party or on the street.

I'm not sure as there's no public information about how it started.
