Yep...it just shows how little I want to work on my essay. The song is from Silent Hill 3, called You're Not Here, by Melissa Williamson. Ignore the subtitle, since I couldn't remove it. Spoilers. It shows Dio and Lucciola and Claus, plus things from the last episodes. Be warned. And it isn't the best-fitting song...sorry, had no Enya.
Pairing: Dio/Lucciola...and Claus. All depending on your dirty imagination.
