A/N: Thanks for all the reviews guys. Unfortunately, I only got one review telling me what they wanted. So, the couples are as follows: Addisex, MerDer, McStizzie, O'Callie. I think that's it. :D This is the way it works. Every chapter will be how each couple spent the day. :D. Starting with my personal favorite, ADDISEX!!!!!!!

Addison clacked down the hall, appreciating the feel of Alex's eyes on her legs. As much as she hated that she liked her intern, she just couldn't shake the feeling. It was that quivering feeling at the tips of her toes when he looked at her. The way he looked at her made her feel beautiful, whether she was in scrubs or Prada.

Thinking about it made her tingly inside.

"Dr. Montgomery?" he asked, making her insides twist. "Are there any surgeries today?"

She smiled at him, and she thought she noticed his face redden a little. "I was actually going to let you perform a C-Section by yourself today. With me watching, of course. In case you mess up," she smirked.

He smiled cockily. "I don't mess up," he said.

"What was that I heard about you freezing up in the elevator?" she asked, almost grinning at the obvious flush of his face.

"I was just letting George have his moment in the spotlight," he clarified, trying to act as if it was his honor.

"Uh-huh, sure," she said, turning away to hide her laughter. He frowned at her retreating form and hurried to catch up.

"Karev, I need you to check on the Summers's baby in the NICU," she said. "I need to prep the patient for surgery. I'll page you. Ok?"

Alex nodded. She turned and left. He watched her hips swing with his head tilted to the side a little, as if he was pondering something complicated.

"I see that," Meredith said, brushing past him. Alex cleared his throat and walked down the hall to the NICU. He stood next to the baby, and slowly put his hand next to the boy. He started humming a song he had heard on the radio on his way to the hospital.

"When I hear our favorite song, I know that we belong…" he sung softly to the baby, Jeremy, whose tiny fingers curled around his big finger. "She is the music in me."

Addison watched from the doorway. "Who is the music in you, exactly, Karev?" Alex jumped slightly. He turned quickly, causing Addison to smirk.

"Nu-nu-nothing," he spluttered, looking quickly at his feet. "Its just a cheesy Disney song. I thought little kids liked them."

Addison didn't move, she just stared at him with that smirk on her face. "You changed the words," she said.

"What?" Damn. I didn't think she knew the words.

"The words are, 'You are the music in me', you said, 'she is the music in me'." Addison raised her eyebrows as if daring him to contradict her.

"Look, Addison," Addison looked up, alarmed by the use of her first name. "It's just a song, don't read too much into it," he went to walk by her. When his shoulder touched hers he heard her sing, softly, "You are the music in me."

Mmhmm. Addisex. Short chapters. There will be two chapters for each couple. Then one big chapter for the end of the day. :D. oh, and im thinking of writing a book. Review and tell me if it's a good idea.
