The Traveler aka Aether was on the search for his sister named Lumine, along side with his floating companion named Paimon. His only goal was to find his sister and leave. That is until he met you in Inazuma. You were the sunshine in his dark travels, you made his heart race and his face all red. Aether quickly fell in love with you, but you didn't want to get in the way of his mission on finding his sister

Currently you are braiding his hair as Aether hums a tune. You then told Aether that he should focus in finding Lumine instead of focusing on you. That's when Aether responded to you

"Once I find my sister, I'll leave her behind so I can be with you."
