[ Being the serious person He Xuan is, he's opening his mouth to say something to that, and then he realizes that the other male is cracking a bit of a jest, closing it instead. It probably looks a little comical, in retrospect, but it's fine.

Instead, next he's watching as Tartaglia's reaching for...what, a strange mechanism of some sort? He isn't quite sure what he's looking at here. And then there's the picture going off.

It's not the most dignified image of him, but there have been far worse portraits made in his likeness. It does manage to tear the scowl off of his face, as he's reaching out for it. He does like it, his sulky face, alongside Tartaglia in his wonderful maid outfit and all. ]

I promise. No one else needs to see it.

...Didn't know there were devices that could make immediate portraits, however.

[ He Xuan hasn't had much interest in unfamiliar, more advanced technology, but this is an outlier. ]

I'd say it was him, but I suppose my actions at a certain...place ended up causing it. Initially we got along, because on the surface, our personalities are similar. Yet, we ended up having certain irreconcilable differences.

[ Suffice to say, so maybe it was him who started it? At the time when he was at the hotsprings, He Xuan didn't exactly view Diluc in the same way as he does now. ]

But, seems his reasons for him disliking you are obviously different.
