~Sebastian POV~
I stood there, behind the closed door, awaiting the time in which I would be able to make my move. "Sebastian…" I turned around, watching as the young master steadily approached me… rage very evident in his eyes. "Yes?" I asked, already knowing what it is he wished to say. "Sebastian! Why did you disobey my orders?!" 'Ah, thought so…' I bowed slightly. "Forgive me, my Lord, but I heard a rumor of sorts that young (F/N) was in tears…and that you were the cause of it." He seemed taken aback, but then glared at me. "I did no such thing! I was merely curious about her past and…well…" He looked down, eyes tearing. "S-She and I…" My brow raised as he continued. "…we have many things in common…such pain…such misery…" A sharp pain erupted through my chest. 'Pain…' As my young master began to weep, I patted his head. "I know, my Lord…believe me….I know…"
I put him to bed, finding a way to ignore answering his many questions about my past. "Sebastian..." I looked back as I opened the door to his room. "Yes, my Lord?" He looked down briefly, before returning my gaze sharply. "(F/N) doesn't remember you...but I know that you feel something for her...correct?" I was a bit taken aback by his sudden inquiry, so it took me a few minutes to respond, though unwillingly. "...Yes...I do..." I was awaiting him to chuckle darkly and begin to plan something to humiliate me, 'not that he didn't already attempt that many times', but the response I was given both shocked and enraged me. "...I can see why you would take interest in her..."
It was painfully obvious, now that I looked at her sleeping form (creeper much XD), that she was a person I loved. "…Caster (sorry, you can place another name here if you wish!)….." Her name still fell smoothly from my lips. "(F/N)…are you Caster?" I had thought it was impossible in the beginning, but now…I'm not entirely sure. I thought back, to that dreadful day…..the day I lost her…
"S-Sebasti…an….pl…ease….please!" I listened, pained at the sound of her cries. "St-Stop…pleas…" A large thud resonated around the room, and I watched in horror as crimson liquid made its way down Caster's body. A gashing wound, covering much of her torso, continued to bleed out without pause. "How does it feel, Sebastian~ Are you proud of what you have done?" I glared harshly at the woman before me. She lifted up my chin, a sharp pain traveled through my body, and smirked at me. "Tell me, do you like pain~?" I spit in her face, earning a scratch on my own from her slap. "You insolent!" Caster's cries began to fade now, softer and softer… I watched her body slowly slump over, my own trembling in fear and anger. I was pissed. Pissed at the woman whom took Caster hostage, and even more at myself for o protecting her. "C-Cast…er…" Her lifeless body turned to look at me, vaguely, before slumping forward. "Caster!" My heart was pounding. "Caster! Caster answer me! Caster!" Tears began to erupt from my eyes. "Please! Caster!" It was no use…her body lay there without any response. My mind no longer had control over my body…pure instinct took over.
'That was the first time I willingly changed into my true form…' I can still remember the warmth of the demon's blood as I ripped her to pieces… and a shudder of satisfaction spread through my body. It was wonderful…being able to kill that wretched woman, I only wish I had done it sooner! I looked back down at (F/N)'s face, as she lay restless. 'That was the first time I lost control…and the last time I ever fell in love with a human…..until now…'
