Gakupo was sitting up in bed, reading quietly when Kaito came in, he looked up at the noise of the door closing.
"What do you need Kaito?" Gakupo tilted his head slightly. He looked ill and extremely tired but his voice was strong, that was a good sign...
" Istabbedyou,I'mreallysorryandI'mprettysurethatIwon'tdoitagain."

Gakupo has a look of pure confusion on his face, "Whoa, slow down and speak so that I can understand you."

Kaito nodded slowly and spoke again, "I should apologize to you for what I did. I should have thought before I stabbed you, I'm really sorry and I'm pretty sure that I won't do it again." Kaito's breathing was shaky and tears started to roll down his face. Gakupo blinked slowly before pulling Kaito down so that he could cry on his shoulder.

"H-h-h-ow can you be so kind to me?" Kaito sobs into his shirt, soaking a small area with tears. Gakupo gently strokes his head, trying his best to sooth him.
Gently he brushes his lips against Kaito's and amazingly, Kaito responds. Their tongues dance lightly together and saliva runs slowly down the side of kaito's mouth. Greedily, Gakupo licks it up. Finally Kaito has stopped crying and his eyes glaze over only moments before he falls asleep.

"mmmmm..." Kaito's eyes flicker open, he's lying down in a silk bed, surrounded with warmth. He can hear Gakupo in the baths and decides to go see what Lily is doing. He pulls a shirt over his head, and moves down the hallway towards the dining room. Lily was dusting the living room when he passed by.
"Kaito? I have something that I want to tell you... Sit down..." Kaito tilts his head, slightly, he wonders what she wants.
"It's about Gakupo. You see when he was a child, he was abused and it got so bad that he developed a second personality, a murderous one that became known as Gaken... Gakupo went insane a couple years back. He killed many people, I often came into his room and found him covered in blood, and him licking it off of his fingers. He did kill your parents Kaito, but I don't think that he even knows that he did..."

Kaito blinks slowly, trying to digest the unexpected information. It explained why Gakupo seemed so different every time that he met him. Yet strangely, he wasn't mad. There were no emotions on his face. Lily grew worried, Kaito's eyes had glazed over, but there wasn't any hate there... However, a wave of the hand brought him back to the land of the living.

"Kaito? Are you alright? You looked as though you were dazed..." Kaito didn't reply, he whirled around and moved down the hall, Gakupo would pay... He would pay with blood.
Lily chased Kaito through the castle. When he finally ditched her, he sank into a corner and clutched his face, insanity making itself known in the thin lines of his eyes.
"Hee hee hee. Finally... Finally, you will pay... AHAHAHAHAHAHAHA!" His laughter echoed through the castle, many of the servants looked up and shivered, fear racing up their spines.
Doors raced by him, Kaito held a blade within his hands, he looked as if he had gone insane. The door to Gakupo's bedroom stood in front of him. He pushed it open, hiding the blade behind him. Gakupo looked up and moved over to give him a hug, he didn't understand the look in Kaito's eyes. His arms slowly wrapped around Kaito, then jerked and stopped, Gakupo's eyes had glazed over. Lily burst into the room, but she was too late, a thin blade had been pushed through her young master's body. Gakupo slumped to the ground, eyes closed, gone. Kaito raced past Lily, hurrying down the hall, while her screams echoed around the castle.
