Prompt: I'd even join the bad guys for you
Fandom: Buffy the Vampire Slayer
Characters: Spike, Buffy Summers
Pairing: Spike/Buffy Summers
Summary: Spike would even join the good guys for her.
At first he didn't even know it was happening, but he started spending more time with her stupid little Scooby-gang – sometimes even helping them. He didn't mean for it to happen, but it did. He realized on that night she'd made him promise to protect the only person she cared about, and he told her that he would, until the end of the world.
He was a sodding good guy, and it was all for her; everything for the Slayer.
The Big Bad Scary Vampire had joined the white hats for a girl.
*Guess you always will be love's bitch, William."* The malicious voice from his human years came back, playing on his insecurities.
