A Watcher and a vampire. The ultimate forbidden love...or that's how Wesley would describe it. If he could. But no. Angel hasn't the faintest idea of the Watcher's feelings for him; his desire to be something more than friends and partners. And that's the way it should be. Why complicate things?
Wesley knows and understands the reasons why he and Angel could never really, truly, be together. Hell, it's not because they're both men; Angel was known to enjoy the company of males when he used to be Angelus. Spike is proof of that. Why, the blond vampire even dropped hint that he and Angel had been intimate in the past. Angel, meanwhile, only shrugged it off, but he never did outright deny it.
Angel will, forever and for always, carry a torch for Buffy Summers, the Slayer; his "forever love." Wesley, despite himself, felt a small part of him ache whenever the brunet vampire would bring her up. If only he were so lucky. Wesley wasn't surprised to discover that he was jealous of Buffy. He would love for Angel's face to brighten up at the mere mention of his name.
But alas, it was never meant to be, really. He could still admire and pine from afar. As long as he's a part of Angel's group, Wesley could deal with it. As long as Angel needed him, whether it be for research or backup, it was perfectly fine. Except that it was not.
He wanted more, but Angel didn't. And he was going to have to learn to cope with that fact...eventually.
