As long as you could remember, Paimon had been your sister for as long as you both had memories. The moments with her were the best, she made the world feel less heavy and alone in all of Teyvat.

Since they met Aether or "the Traveler", they had a little more fun, danger, adrenaline and so on. They have a good friendship with this young blond, your older sister has always worried about him just like you.

Getting ahead of the facts:

When they arrived in Sumeru, because of a scholar's incense, Aether fainted and with the help of a scholar named Tighnari, they were able to take him to Gandharva Village.

But Paimon was angry, Angry? She was furious with that forest ranger! He was scolding her all the way to that village, she didn't like that attitude. When they were alone, she let out her anger:

"Urrghh! How dare you...?! Ugh, by the Seven!"
