Cristina took a deep breath as she just stared at that door. Starting at it, she could vividly remember the last time she knocked on it.

Five Years Ago

"Come in," said Chief Hunt as he heard someone knocking on the door of his office. He looked up from the file he was reading to meet the eyes of the other person. "Oh hi," he said, smiling slightly.

Cristina smiled slightly as well and she nodded. "Hey," she said quietly.

"Come on, sit," he said, motioning to the seat in front of his desk. She nodded again and went to sit on where he motioned too. Wringing her hands, she was reviewing the speech she was gonna give for the hundredth time.

He gulped and then looked around his desk and then grabbed a plate and placed it at the front of his desk. "You want some…" he started, "… fresh banana bread."

Cristina looked up and looked at the plate, knowing exactly who had baked it. She shook her head, smiling. "No thanks."

He nodded then there was another awkward silence between them. It'd been almost a year but he still couldn't help but feel awkward around her. They used to be good at the beginning of this one year, but after that day that he noticed her witnessing him and Emma in the lobby, kissing, things had gotten slightly awkward. "So… what's up?"

Cristina sighed a sigh of relieve, as if she had been waiting for him to ask that question so she could free herself by letting the words out. She nodded and pulled a paper out and then placed it on his desk. "I'd like to turn in my… resignation," she said, not even daring to look him in the eyes and see his reaction. "I've got a job offer in… in Paris and I'm… going."

Owen just stared at the paper in front of her and then looked up at Cristina. "Paris…? F-France?"

Cristina nodded. "Yes," she said finally looking at his eyes, reading nothing but pain in them, which wasn't anything new. She had been seeing that pain in those blue eyes for a year.

"Is it… because of me… that you're going?"

"Partially," she answered quickly, as if she had the answer ready. "You and… Meredith and... I just wanna go… away from here. I just want a free mind. There's nothing left for me here. I don't have a reason to stay here anymore. It hurts to look at you and see that you've moved on. It hurts because I haven't been able to move on. And that's not your fault. You did the right thing and I think maybe by going away I can gain the power to finally move on. And Meredith doesn't even look at me and I feel invisible sometimes. Everyone is having their own life. And nobody can include my problems in their life, not that I need anybody to do so or expect them to, but it will hurt less if I go somewhere where nobody knows me. Somewhere that I don't feel invisible. It'll hurt less. So I don't care how you feel about this. I just need you to sign that resignation because I have plane tickets for tomorrow night and I have all my stuffs packed and I'm going to Paris." She stopped rambling and took a deep breath and then she realized what she'd said. She was surprised by the words that had come out of her mouth. She had spent the whole day, preparing what she was gonna say to Owen and those were nothing like what she'd prepared. She never wanted to say those.

She looked up at Owen and jumped up from the seat. "Just tell me about your decision later," she said and rushed out of the office, leaving Owen there with an opened mouth and pained eyes.

"What is the entire luggage about?" Alex asked as he stuck his head in the doorway of Cristina's room. Cristina looked up from her suitcase and met Alex's eyes. "Uh… I was gonna tell you tomorrow… didn't think you'd come home tonight. Uh… I'm going actually… away… leaving…"

"What?" he asked frowning.

"I've got a job offer in Paris… France."

"France?!"

"Yes,"

"But why? What's wrong with here?" he asked as he walked in her room.

"So many things Alex," she said, smiling sadly, "And you know about it. Everyone knows about it. I just can't take it anymore. I… just want to leave…"

Alex nodded, understandingly. He, wanting to show her his support, put a friendly hand on her shoulder. "Don't forget me when you go," he said, smiling a bit.

She smiled as well. "I never will," she said, the corners of her lips turning downward and trembling and tears welled up in the corners of hers eyes and she sighed.

"Hey," he said. "Cristina Yang doesn't do weak and emotional, does she? Don't cry." He was trying to cheer her up.

"I don't think I'm a robot anymore," she said, shaking her head and her tears flowed free suddenly.

"Of course you're not. I know you're not." He said, wanting to comfort her. Her rubbed her shoulders and finally gave in and pulled her close, hugging her. "Shh…"

"Passengers of the flight AF3209, to Paris, please have your tickets checked-in," said the information desk of the airport. Cristina had just arrived in the airport when she heard this. Hurriedly, she walked to the gates to check in. Alex was running behind her with the other half of her stuff. "Would you please slow down?" he yelled from behind her. "I don't wanna be late," she yelled back.

Finally they were at the front of the line and gave her baggage to the desk. Cristina then rushed to the other direction to go to the line for the transit hall. As they reached the line, she turned around and looked at Alex. "So… thanks for helping me out…" she said smiling.

"Hey, it's no problem," he said, smirking. "So…"

"There's e-mail and Skype and phone, you know? I won't forget you." She smiled.

"I know," he said, nodding. "Come here." He pulled her in a hug. "I still hate you though," he said laughing.

"I do too," she laughed as well. "You're a good friend, Alex," she said after some minutes and pulled back.

"So are you," he smiled. "So… goodbye…"

"Goodbye…" she smiled and with one last, short hug she went and stood in the line. And he started to walk away.

After some minutes, it was finally her turn to show her passport and ticket to the clerk. Before she did so, she turned around and looked at the distance, subconsciously, expecting to see someone familiar there to say goodbye to her. Actually one familiar person. But as far as her eyes could see, there was no one familiar there.

"Ma'am?" she heard the man say and turned around, giving him his ticket and passport to check. "You can go in." he said and gave her, her ticket and passport back. She was taking a step in to the security door, when she heard her name being called. She turned around fast and saw him, there, looking directly at her. "Owen?"

"Don't you go in ma'am?" the clerk said and she turned to look at him. "G-give me a minute?" she asked. The clerk took a breath and then looked at the blond man in front of the gate and then back at her. Hesitantly, he nodded. "Just be quick," he said and she nodded, going toward Owen fast.

"What are you doing here?" she asked him, frowning.

"Saying… goodbye." He said looking down at her. Not able to say anything, she just stared at him. His blue eyes. She just let herself drown in the ocean of his eyes, for one last time. Was she not gonna see him again? Was she not gonna see that vast ocean again? The thought of it just made her heart ache.

Not even caring about it, she let a tear roll down her cheek. "Goodbye," she said her voice breaking.

He nodded, looking down at her. Seeing tears roll down her cheek, he could feel his heart hurt. Was he not gonna see her again? Was he not gonna smell the rose of her lips again? He hadn't though, in a year. But he always had hoped that he one day would smell the rose of her lips again. But now, she was going to go forever. To another country. Another continent. Now it felt so real and so unbearable. "I may seem to have moved on, but… you wound yourself around my heart so deeply that I can never move on from you. You healed me, you made me a better person. I can never pretend our five years didn't exist. I Just pretend to have moved on. I will always love you. Even if you're not enough for me, I can never love another woman as much I do love you. Go, I can't stop you. But never think I can ever forget you. Just know this." He said, tears welling up in his own eyes. "Goodbye, I wish you the bests."
