"You ready?" Derek questioned excitedly as he guided his long-term girlfriend to the door of their office.

"To finally see the masterpiece?" Casey joked.

"But you see that every day," Derek pointed out slyly, smirking as he regarded himself.

Casey rolled her eyes and elbowed him lightly in the stomach. "Come on, Masterpiece. I want to see what had my boyfriend hauled up in this room for the last few days before Christmas."

Derek opened the door to their office, stepping back to let Casey walk in before him.

"Oh my! Derek! This - this is amazing!" she genuinely praised, walking around the table he had set up in the middle of the room to place his massive gingerbread structure on.

It was a castle-like building with an obvious inspiration from Cinderella's castle. It was laced with candy-canes, peppermints, gumdrops, and some other candies. The whole structure was so colorful and grand.

"You like it?" he asked, coming from behind her, only to wrap his arms around her waist. He pulled her back against his chest and gave the back of her head a tender kiss.

"I love it," she expressed softly, still in amazement and wonder that Derek held this kind of craftsmanship.

Derek smiled. "Well, Merry Christmas because this is for you. Every princess needs her castle, no?"

Casey turned around in his arms, smiling brightly up at him. "Thank you," she told him before reaching up to give him a kiss.

"You're welcome," he said back after their kiss ended. "But there's one more thing I have to show you about the castle." Casey furrowed her eyes brows in confusion, wondering what more could he possibly have to show her.

He then unlatched his arms from around Casey, having her turn around and walk up closely to the display. "You see the door?" he asked, pointing to the big entrance door of the castle. Casey nodded, looking at it. "Open it," he instructed lightly.

Casey hesitantly went to reach for the door, hoping to keep her klutzilla tendencies at bay so she wouldn't accidentally hit something and have the whole thing crumble and break. When she finally was able to pull the door open, she saw there was a smaller gingerbread structure that looked like it was supposed to be a carriage.

"Aw," she said, picking the object up.

"Now look inside of that," Derek instructed further. His voice, she recognized, was almost a whisper now, but she ignored it since her curiosity was stronger.

As Casey brought the carriage up to her eyes, she saw something shiny resting in it. She raised an eyebrow and took one of her fingers to pick the item out. When her finger finally touched the object, Casey eye's popped open wide in shock.

"Derek?" she called out breathlessly as she stared down at a ring. A ring with a massive diamond sitting on top of it.

She turned around to face Derek for a further explanation, but he was knelt down on one knee in-front of her. He took the ring from her fingers with a shaky hand, and then looked up at her with the most fear she had ever seen him possess. "Marry me, Case?"

She immediately nodded her head, happy tears spilling from her eyes. "Yes," she was eventually able to choke out. Derek let out a sigh of relief as he slipped the ring on her left ring finger. They embraced with utter joy.

"Thanks for making this the best Christmas ever, my prince," Casey told Derek, her arms around his neck, while his were on her waist.

Derek groaned. "Cas-eyy, don't make this corny," he pleaded.

"Derek! This whole proposal was corny!" she pointed out.

"Exactly, so don't make it cornier," he implored.

Casey opened her mouth to say something else, but Derek quickly muted her with his lips. She responded back, not being able to help herself. Derek smirked against her lips, happy that she did.

"Corny," Casey teased in-between kisses.

"Shhh. It's kissy time," he told her as he hoisted her up in his arms to carry her to their bedroom to further celebrate.
