you were Aether's guardian after he saved you and you two traveled together from then on

one night you were cooking dinner and paimon was trying to set up the tent. You were currently in sumeru. But Aether? He was nowhere to be found..

you excuse yourself and get up to find him. As you go to nearest lake to have better view you spotted Aether's clothes on the ground..as you looked over at the lake you saw Aether swimming in it?! *as he turned to you he just waved without embarrassed
