I don't really know how to explain it. I look at a guy's eyes, hair and personality. To me, he is pleasent to look at and he is really funny. That is why I think he is cute. It's a personal taste thing though.
I tend to be attracted to the guys that are clumsy... he means well but most of the time he doesn't quite get it right. He's also very talented and loving.
I think jiro is cute not because of how he looks but I just feel like he gives off the vibe of being a good sweet guy not many of those are left in this world. Jiro seems to me to go through so much just to make his hopes and dreams a reality. Plus he takes care of his family how many guys really even do that anymore.
