[Mondstadt certainly had far more stormy times in its history but for these days Ayato is quite right - the weather was milder by far in Diluc's home country than in most others and the people had always prospered for it. It was part of what allowed Diluc's vineyards to bear so much fruit.]

I'm sure Mondstadt would welcome you both. [This has echoes of a conversation he had had with Ayaka before. One she no longer recalls. How interesting that both she and her brother would have such similar longings to see other nations.]

As for imagining... there's no need. I've travelled through Inazuma before. [Diluc shifts to pour the tea, being sure to pour Ayato's before his own.] But I think... you may have already been aware of that.

[His voice stays mild and polite as he hands the young Yashiro Commissioner his cup.]

Or am I mistaken?
