[They need to keep walking, it's true. The rain was quite merciless, leaving them soaked to the bone and Aether is aware that this may cause trouble for them again. He doesn't want any awkwardness to linger, even if he's more than sure Ayato wouldn't be bothered by whatever his actions could be. The other would likely use them to tease the traveler though...

A soft sigh escapes Aether's lips.]

Your expression changed when I talked about Thoma... and then you gave me a pretty distant answer when I talked about him again. It got me thinking.

[But now that he has his suspicions confirmed, and moreover, Ayato mentions feeling jealousy, this leads Aether to another conclusion - that there is something more between Ayato and Thoma than he initially thought. Maybe this is exactly why Ayato was so bothered by being from a different version of Teyvat than Thoma is.

A frown settles on Aether's face. The fact that he shared a kiss with Thoma suddenly makes him feel really bad. He knows it wasn't their fault that it happened and yet it still doesn't sit well with him.]

I can't say I enjoy this place. [He says.] People should be able to reserve their kisses for those they care about the most.
