He is an impressive man.  And I am a very heterosexual man who likes women, but... this dude has some serious dignity, manliness, and grace.  His too-perfect complexion, his hair, the way he wears those perfectly-tailored suits in this show, the way he sits, his body language...  All of it makes me want to BE him.  And he pulls it off; it doesn't feel pretentious or off-putting. It actually feels like he is genuinely that dignified, and it makes you want to have him around.

As a lifetime nerd who has always been "too tall" and "too skinny" and "too clumsy", this dude is pretty much the Ultimate Guy.  At least, he comes across as such in his role as Han Jae Joon.

Maybe I just need some of those suits?
