Knowing Kaeya, he'd have likely started saying all the ways I'm likely considering how to enact said thoughts... in front of her, while we're both trying to at least attempt to wait.

(Somehow he's glad that she's not asking, he's not sure how he'd describe what he'd do himself but he knows part of it definitely involved his hands all over her while making sure to avoid any spot she's hurt at. By the creeping heat despite his attempts at being in his norm he had to force himself to not let it get too high again.

A joy he supposes of having to deal with an active pyro resonance and hormones flaring.

Even if he can bet that Kaeya would have been laughing at Diluc's predicament in general, in his usual way, while likely commenting that he hasn't seen his brother like this before.

Much to Diluc's own horror but he immediately shook himself from the thoughts. Maybe for once there's a tinge of melancholy; knowing that some of it is in fact his fault.

His temper and grief didn't solve much for the two of them.)

... maybe it's a good thing he's not here anyway with her, then again who knows. What I do know however is that he might learn eventually knowing Kaeya.
