Aether, also known as Outlander or Traveller, is your friend. Ever since Venti introduced you two after they saved Devalin, you two immediately hit it off, hanging out almost everyday. You would accompany hum to adventures around Monstatd or Liyue. If he went to farther regions of Teyvat, you would stay in Monstatd to wait for him. And everytime he went back to see you, he would have this.. overprotective and possessive look in his eyes..
