Kill the King (Megadeth)

Grimmjow thinks himself a king. He wants to be treated like it too. I'm honestly tired of it. He thinks he's better than everyone. Better than me. He is no king, and never will be.

"Ulquiorra! Bring me another jacket! This one has blood on it."

He treats me more like a butler than a boyfriend.

Time and time again, I'm treated as if I'm insignificant. Dirt.

I'm in our kitchen, and the bedroom is on the other side of our shared apartment. Closer to him than me. Lazy asshole. I'm not going to be treated like this anymore. I refuse.

Kill the king.

I grab a knife from the holder on the counter, holding it to my side opposite of the one he'd face when I walked by him, before heading into our room and retrieving his jacket with the other hand.

When I take the jacket to him, he merely responds with a "Tche. Took you long enough." while removing his other jacket. He slid the clean jacket on to his shoulders and sat back down; never once catching a glimpse of the knife I'm still holding. I stand behind him a moment longer, waiting for the right moment.
The moment finally came when he flipped on the TV. I put my arms around his neck, acting as if I were merely giving him a hug, still not letting him know I had a weapon until I pressed the cold blade against his throat.

"Long live the king." Was all I whispered as I drug the knife across his throat, allowing his life blood to spill out. I walked around the chair so I could see the expression of shock, hurt, and anger on his face. His eyes were wide and he had his mouth gaping, trying to gasp for breath.

It only took forty-five seconds or so until the King was no more.

"Oh, would you look at that? You have blood on that jacket too."
