I guess I'm just not optimistic about romantic relationships in reality, as I haven't really seen many good examples. And even in fiction, it seems the characters I'm hoping will win never do; in "Cardcaptor Sakura" anime Meiling wanted to be a Cardcaptor and loved Shaoran, but it was Sakura who got to be a Cardcaptor and won Shaoran without even trying. In "Fruits Basket" Kagura really did love Kyo, but it was Tohru who won him, again without even trying, etc. So, in regards to Shiemi, Yukio is at least wise enough not to try.
