Unfortunately, it's not that easy. He hasn't quite determined how to come out to anyone, even Sebastian, the geeky-hot TA in his history class. Sebastian is everything Brad is not. Intellectual, suave, hairy. Out. And he doesn't seem interested in Brad, even when Brad makes a fool of himself trying to catch his notice.
Score one for foolery: Sebastian does more than notice Brad; he takes him to bed. Brad's been with plenty of girls, but with Sebastian, the sex is something else entirely — hot, mind-blowing, affirming, and a little domineering in a way that drives him wild. But when great sex turns into something more — dare he admit the "L" word? — Brad must face the crushing realization that Sebastian doesn't feel the same. Unless, of course, he does. After all, even grad students can be idiots about matters of the heart.
