The element of enemy isn't something you should think of as bad. You have to have the "enemy element" if you are to have lovely, dreamy, and beautiful things too. This is a good word when you're talking about some dude you think is hawt. Doesn't work as well with girls.

This is a jukugo word, which usually means on'yomi readings from the kanji. You haven't learned this reading for 素 yet, so here's a mnemonic to help you:

Oh wow, you look really lovely in that suit (す). Yes, I can see you through the Internet, and I have to say, that suit is just dreamy! Don't ever take it off.
