In this universe, Seto never gave Alissa a promise ring and actually wants to get married. They've also been dating for five and a half years. You guys can probably guess where this is going now.

"Can you pass me another ornament, Seto?" Alissa asked from her place on the ladder.

"Which do you want next? Ball or Duel Monster?" Seto asked.

"Um, give me a Duel Monster I guess. We don't have many of them up here yet."

"Be careful up there, you're making me nervous."

"I'll be careful, thank you." She grabbed the Kuriboh ornament from him and placed it on the tree.

"What time are your friends coming over tomorrow?"

"I told them four. Thanks again for letting us have Christmas dinner here this year. I know you don't really like them that much."

"I don't really like anyone except for you, Mokuba, and Roland." She laughed.

"Well gee, I'm flattered."

"As you should be, the list of people I like is a hard list to get on."

"Stop making me laugh and hand me some more ornaments. I still have some wrapping I need to do before tomorrow."

"We're almost done. We only have a couple more."

"Okay, pass me another Duel Monster and a ball." He handed her a blue ball and a Cave Dragon ornament. She hung them on the tree next to each other then held out one of her hands.

"Hand me the Blue Eyes ornament. I know that one is your favorite so I'll put it on the highest branch." He smiled and handed her his favorite ornament. He watched her as she stretched her arms to reach the top branch. He slipped his hand into his pocket and ran his finger along the edges of the small box.

"How many do we have left now, Seto?"

"One." Well, here we go. He reached into the ornament box for the new, custom ornament that he had made specifically for this night. He handed it to her and she frowned in confusion when she realized the ornament wasn't a ball or a Duel Monster. She pulled the diamond shaped ornament closer to examine it. The ornament was made of blue, airbrushed glass in the shape of a diamond. The ornament was hollow and inside there was a smaller blue heart. In beautiful, curved letters inside the heart were the words 'Will You Marry Me?'

"What? Seto is this-." She stopped when she looked down to find Seto on one knee and holding a small black box with a glittering diamond ring in it.

"I prepared a speech, but I think the ornament explains it all."

"Seto-."

"I love you, Alissa. I want to have a life with you. Will you marry me?" She stepped off the ladder, placed the ornament on the coffee table, and put her hand son both sides of his face.

"Yes." With her answer, she leaned forward and pressed her lips to his in a loving kiss. She pulled away slowly and he slipped the ring on her finger

"I love you," she said before pulling him to his feet and kissing him again.

"I love you too." The two stood in the living room, embracing each other tightly. She extended her arm out behind him so she could look at the ring. Hm, Alissa Kaiba. I like the sound of that.

Yay engagements! It took me a good while to figure out a way for him to propose that would fit both his and her personality. Since he's a private person for the most part, I immediately ruled out the idea of a public proposal. But I also know that Alissa has a very romantic personality, so the proposal would have to be something romantic but not too showy. Thus, I came up with this idea and I think it fit both of their personalities pretty well. Anyhoo, another theme down, five to go.
