(A/N: This story will be based on the eery CG scene from Laito's Manservant ending in More Blood where he basically catches Yui being bitten by Kou, knocks the two of them out and chains her up in the dungeon. There will be quite a bit of graphic scenes in this fic. You've been warned! Enjoy~)

Prologue

Yui's eyes fluttered open. Her head felt heavy and there was a dull throbbing at the back of her skull. Her half-lidded eyes searched around through the darkness.

I..can't see anything. And it's freezing.. Where..am I?

She shivered and tried to pull her limbs to cover herself, but her movements were stopped. The rattling of chains echoed through the pitch black room.

"What the..? What is this-!" She said in confusion and tugged her arms once more. But they would not budge.

"Ahh~ You've woken up, Bitch-chan?"

She flinched at the sudden voice and looked around.

"Laito.. Kun?" She called out.

A light flickered on above her head, just then. She gasped as she met with his illuminated face, just inches from hers.

"Correct." He grinned and took a step back.

She knitted her brows as she watched him walk over to each corner of the room and light the lanterns that hung from the walls. She was in the dungeon. But why?

She squeezed her eyes shut as the throbbing pain in her skull began to intensify.

"Ugh..! Laito-kun.. My head..! What happened?"

Laito blew out the match and stomped it into the ground with his shoe. "Nfufu.. You were knocked out.. so how can you remember? Fufu.. Well, I'll tell you everything."

Yui's face contorted in confusion. Her heart began to race inside her chest as the vampire approached her with a chilling smile. He knelt down beside her, reaching out a hand to softly caress her face.

"Even though you had claimed to love me.. you did pleasurable things with that guy."

His green eyes flashed as they met with hers. "So I brought you, along with him, in this torture chamber."

"Torture chamber!? With Kou-kun? But I don't see him.. What did you do to him!?" She shouted.

Laito's hand fell to his side, his smile slowly fading as he watched the girl's rose irises frantically darting around the room.

He let out a dry laugh and stood from the ground. "Why do you care? He's not to your concern."

Yui's mouth hung open as she tried to think of a proper response.

"W-well, he's a person I know, that's why!" She stuttered. "I'd be just as worried if something happened to one of your brothers!"

"Don't." He replied flatly.

Yui was severely confused. "But, why-?"

Laito looked up at her. "Why? Because you have me." He said; his tone implying that it should have been obvious.

"So, I can't allow it. You can't see other men. You can't be touched by them." He explained. "Only I should be reflected in your eyes. But no, just me isn't good enough for you, is it?"

His expression grew cold as he reached behind his back. Yui's eyes went wide as what he pulled out fell into her line of sight.

"R-Relax, Laito-kun!" She cried out. Her voice began to tremble as she spoke. "You're holding a k-knife.. w-what do you plan to d-do with it?"

Laito remained silent as he stared down at the blade, turning it slightly in place. He looked up at her, his green eyes glinting with malice. "Fufu.. Hey, Bitch-chan. A silkworm would know."

Yui looked taken back for a second. "A silkworm..?" What on Earth was he talking about?

Laito nodded and took a step forward. "To make silk, the insect is kept by humans. Silkworms are domesticated into perfection. The instincts of the insect are forgotten, it survives for only one purpose, killed when they are no longer needed."

A smile smile graced his lips. "The worms wish for it too, because the person profits from the insect.. and that is love in its ultimate form."

Yui pulled at her chains as he closed in on her. "S-Stop..!"

His smile grew wider. "We'll have the same form of it, just like a person and a silkworm.. will you become an insect for me? Fufu. That way, you and I will find happiness. Isn't that the foundation of a wonderful and mutual form of love?"

Tears prickled in the corners of her eyes and she desperately tugged her arms to get free.

Laito's cheeks flushed as he gazed down at her. "Heh heh heh. Bitch-chan, you're so cute. Do I have to give you an idea as to how much my love goes out to you? I love you so so very much."

He knelt down beside her, and nuzzled his nose against her shoulder; his hands slowly trailing up her sides.

Yui thrashed and kicked, but she could not move an inch. The red headed vampire had her caught in his grasp. He giggled and placed a chaste kiss on her lips. "It's useless to try to run away. You'll be my butterfly..only my..beautiful butterfly."

Her whole body shook as his fingers laced through the red satin bow on her uniform, pulling it from her collar and popping open the buttons of her shirt.

"Now, forget everything.." He whispered. "Let's try to make you feel good.. okay?"

He let out a low laugh as he tugged her shirt open, his breath trailing up her shoulder onto her throat. She inhaled sharply when she felt the tips of his sharp fangs at her skin.

"You are forever.. going to be kept by me."
