[It's just like he thought - Thoma only has the best intentions in his mind. Aether doesn't want to disappoint him, but at the same time revealing one secret would lead to more questions, more worries. Thoma has his own life, he shouldn't be wasting it concerned about a traveler that one day may vanish without a trace.

Aether takes a deep breath in and out.]

For as long as I can remember I was always travelling. Even before Lumine and I were separated we would visit many places together, sometimes staying for longer, sometimes leaving right away.

[He doesn't look at Thoma as he's speaking.]

But as much as I enjoy the journey, I'm also looking forward to the day it will end.

[He smiles, but there is no joy in it.]

Everybody longs for "home" and I'm no different.

[But is there really a place out there that could accept both them? It's almost funny that despite everything that happened, a part of him wishes they could stay in Teyvat. There's so many people who have grown so close to his heart, there's Paimon who promised to always be by his side.

Aether's smile is warmer when he looks at Thoma.]

Here. This is my silly secret.
