Just for a slightly different point of view, because I know many of you are older than Yuzu, but as a 16 year old girl, he is very much a 'typical guy' to me. It might be because he's so much older, but the way he dresses off the ice and the way he talks is pretty on par with the college guys in my area, and I live in Asia at the moment.
He may show a more feminine side in his programs, like in haru yo koi, but he still screams 'I'm a male in my early twenties and I should be in college' to me. He has a very boyish charm, but doesn't seem that different from any other person his age.
He's very driven and admirable, and combined with his skating and boyish charm is probably why I have such a massive crush on him *hides*
Like I wish guys like him were interested in me.
Just IMO, he seems straight and very, very comfortable being male.
Disclaimer in case of misunderstanding: I do not in any way think that being anything other than cis and straight is abnormal in a bad way, da da da da da...have no intention to offend anyone.
