That night the twins hardly spoke. "Alright. Why haven't you talked to me all night?" Len asked from the desk in their room. "What do you mean?" Rin looked up from the manga she was reading on her bed. "You usually talk my ear off. Though I prefer that to this silence." Len said while closing his latop to look at her. Rin looked away from his.
'Why did she keep doing that?' Len closed the note book he had been writting in, and walked over to sit on Rin's bed.

"Rin. Were family... if something is troubling you. You can tell me." Len pulled Rin into his arms.
"I'm your twin. You can trust me with your life." Len rested his face in Rin's hair.
Rin hide her face in Len's neck. Len felt wet tears dribble down his neck.
Len held her tighter, and carassed her hair. He wanted so much, to take the pain away from her.
He wanted to make the evil that caused his sisters pain to end. "Len... t-thank you..." Rin whispered into Len's shirt. Len kissed the top of Rin's head.

"Will you tell me why you have been avoiding conversation with me?" Len whispered.
Len felt Rin nod. "The rules... I hate them..." She whispered. Len felt his heart squeeze.
"Why do we have to follow them?... they don't make any sense... I always have to watch myself... careful not to slip up." Tears began to fall from her eyes again.
"They don't make any sense to you... but to the students at school and to their parents...
it makes sense. Twins... can't fall in love." Len said, his heart heart feeling heavy.

When they had enrolled into high school, people looked at them with disgust. They didn't understand that it was wrong to act the way they did around each other. They were robots.
They were programed to love each other. Rin was created to rule the yellow country, and Len to stay by her side. They screwed up before, when Len had to kill the princess of the green country. They had been reborn to live in a peaceful life. Whithout violence.

"Len... a boy from school called us Twincest. Before class I slashed his tires." Rin whispered.
Twincest. Thats what everyone called them. "Okay..." He whispered back.
"What? your not angry? why?" Rin sat back and looked red eyed at him.
Len sighed. "I'm tired... I'm tired of all of them... I'm tired of pretending to be something I'm not."
Len looked fiercely at Rin. Rin looked shocked. "You mean..." She started.
"Yes, Rin. Let's break the rules." Len shifted onto his knees and connected his lips to Rin's.
Len could feel Rin's happiness flow through him.
This is what they were made for. They were Vocaloids. They were the products of a scientists lonley single nights. They didn't have to follow rules.
