sorry, that won't happen. To literally quote canon, not even his friends ask him that and, the one time they did ask, he said. "Please be patient for a little while longer. I'm not ready yet."

We don't know what's under that hat. It could be cat ears, given how the flaps emote with him. But, supplementary material shows a faked skeleton of one of his people with horns... and none of them thought that was weird.

I suspect horns, to match his brother.

It we do do that, then we'd have to handwave it, with blushing on at least his part.
