"Waking the Demon" by Bullet For My Valentine-What's the story?

"Waking the Demon" by Bullet For My Valentine is all about revenge and karma. The video begins focusing on a teenager who is getting teased by another group of boys at school. As they mess with him, a girl watches, acting as if she is not impressed. After the boy is slammed into the lockers, he smirks and crosses off a day on a calendar. Bullet For My Valentine sings, "You've sealed your demise when you took what was mine." Obviously, they are suggesting that the boy will take revenge on those who are teasing him. However, what is Bullet For My Valentine referring to when they mention possession of something? This is later revealed in the video when the boy gets his revenge. Throughout the video, the boy continues to get harassed. Each day he marks off on his calendar, counting down the days. The girl who seemed uninterested at the beginning of the video is then shown, suggesting that perhaps she is that possession. This is suggested because Bullet For My Valentine sings, "Caution/ there's no limits to the boundaries you push/ I warned you but you still F*ck with my mind/ there's no escape from this rage that I feel/ nothing is real," while the girl kisses one of the boys that has been harassing the main character. When the bridge comes, the boy circles the 28 on his calendar, which is a full moon, suggesting that this is when he will get revenge. The bridge hints that something is going to happen, like he will lose control. As the song continues, the boy does get his revenge by turning into a werewolf on the 28 and killing the boy who teased him, which is suggested by the blood on his mouth, and also from the missing posters in the school. As the song concludes, the boy is teased by another, new antagonist who tries to impress the same girl. The girl is obviously the antagonist's girlfriend, however, it is hinted at that she is in conspiracy with the werewolf boy because they exchange a glance and he smirks. This video, overall, represents the way karma works. If one is treated badly by another, the other will eventually get treated badly in return.
