The characters are all human. Emmett and Bella are brother and sister, Alice is Bella's best friend, and Rosalie, Jasper, and Edward are all brothers and sister.

We walked into the bar and immediately Rose ran up to the biggest guy I have ever seen. He had to seriously work out, there was no other reason for him to be that big. But he had this goofy grin on his face when he saw her, and I knew that he cared for my sister, deeply. The look on his face said it all. Jasper chuckled beside me, and I knew he was thinking the same thing.
I heard giggles coming from farther down the L-shaped bar, and one girl called out "Em, you look like you've been drinking silly juice!" The couple ignored it, but I looked to see who said it. The girls had their backs to us, but they were both brunette; one had long, brown hair the color of mahogany, the other black hair cut in a pixie look. They were laughing together, and I wondered if one of them was Emmett's sister.
Since it didn't look like Rose was going to introduce us anytime soon, Jasper and I decided to sit down at one of the tables and watch people play pool. There were several people that were quite good, and it was entertaining to watch them. Eventually, Emmett came up to us and introduced himself, asking if we wanting anything to drink. We both ordered beers and asked for an open table. He gave us some balls and told us to pick our cues from the racks on the wall.

After Rose and Emmett came up for air, she came over and sat me Alice and me. We teased her a bit, but only out of love, because we knew she and Emmett made each other happy. The bar started to get crowded while we were talking, and I was relieved that the darts session seemed to be off.
We were getting some looks, but that was nothing new. People always looked at Rosalie, who was so lovely she could be a model, or Alice, because she had such energy and grace. People looked at me because they wondered why I was friends with such beauties. But as long as they just looked, it was fine. Even Emmett left them alone.

Emmett joined us for a little while on his break. "Guys, are you noticing how many people are staring at the girls?"
"You mean Rose? People always stare at her" Jasper answered. It was true. Rose didn't mind all the attention, but she had taken some self-defense classes, just in case.
"Not just her. They're looking at Bella and Alice, too." He turned and pointed at the two girls who had giggled earlier, and I swear my heart stopped. The one with long hair had turned so her profile was to me, and I could tell she was gorgeous. Her looked smooth and unblemished, and like it had never seen the sun. Her eyes glistened under the lights of the bar, and were the same warm brown as her hair. Her lips were tinted from the cranberry drink she had, and were perfectly shaped. All I wanted to do was run up to her and kiss her.
Jasper gripped my shoulder, and whispered, "The pixie, Edward…I think I'm in love."
"I'm glad you like her, man, 'cause I like the other one."
Jasper, ever practical, asked, "Which one is Alice, and which one is Bella?"
Emmett answered, "Bella, my sister, has the long hair. Alice is the one that looks like a dark-haired Tinkerbell."
"They both single?"
"Yeah, they're both single." Now he turned and looked at us. "Hey. Alice is as good as my blood, and Bella is my responsibility, so you both better watch it. I don't care if you are Rose's brothers."
Just then, we heard the sound of glass breaking.
