The Magic Milkshakes shop in the high street didn't look like it was supposed to be there. It looked shabby, worn and run down, nothing like the shiny, pristine condition the other shops were kept in. Some people thought it was an embarrassing blemish on an otherwise clean market square.

Another thing that Magic Milkshakes didn't have in common with the other shops was the insides. The rest of the shops didn't care for interior design when they could paint the entire shop one colour and be done with it. But whoever designed the interior of that café clearly knew their stuff. It was furnished with matching red chairs with padded yellow seats, and the walls were painted a lovely orange, like the sand of a desert. The tables and counters were a dirty pink, like the very start of sunrise. And the milkshakes really made the customers know why the word "magic" was in the shop's name. They were creamy, full of flavour and tasted natural. Nothing bad could be said about them; they were perfect.

Despite the appearance from the outside that told you the shop had seen better days, there was still a steady stream of customers coming in, searching for a sweet cup of goodness. Old couples looking for a quiet place to stop by for a snack, parents with young children who were in need of a break, high school sweethearts on a nervous first date - you say it, they were there in the café drinking a glass of chocolate milkshake and telling each other about their day.

Sally and Quinn were best friends . . . well, to anyone who didn't look closely, that was how it would seem. Sally and Quinn were polar opposites in every way: Sally was the athletic one with short blonde hair and killer fashion sense, while Quinn was rather overweight with long brown hair and wore the same kind of frumpy sweaters every day. Sally only kept Quinn around for two reasons: she had a reputation for being a mean girl and wanted to change that by being friends with someone she had nothing in common with and because Quinn was so unattractive it made her look better in comparison. Once the two were alone, Sally would bully Quinn to the point of tears and then blackmail her into silence. And a quiet place like this café that was barely on the map was the perfect place to do it. The fact that it was the school summer holidays didn't hurt either.

"Quinn, stop embarrassing me like that," Sally was heard saying the moment she walked into the building, Quinn three paces behind her, as per usual.

"What did I do?" Quinn whimpered, already preparing for the verbal onslaught Sally would unleash.

"Aww, you don't know what happened," Sally mocked. "Well, I'll tell you what happened. When we were going into that nice make-up place that everyone knows about, your fat ass was too slow to keep up with me and you were gasping for breath the moment you came in! I saw someone looking at you like you were disgusting!" Quinn froze with shame. "Just forget about it, I'll get our order. Find us a table, wait for me there, and think about how you could maybe not humiliate me in front of so many people."

Obediently, Quinn took a table where her chair was as close to the door as she could get it without being too close to Sally, while her friend got their milkshakes. Behind the counter was Zia Minh, a Chinese lady behind the business' success. Nobody could ever guess her age, simply saying she wasn't young, but not old, either. She was of average height and weight and was very fond of her customers. So when she saw this rude girl insult her friend the moment she walked into her café and then refuse to let the tormented girl make a decision as simple as what order she'd like - well, Zia couldn't let that happen. "Good morning, miss," she said, with forced politeness. "What would you like to have?"

"Do you do smoothies?" Sally asked.

"Yes, we do, miss," Zia answered, happy to have the vain girl's attention. "Our smoothies have their own section on the menu."

"Thank God!" Sally exclaimed. "A girl's got to watch her figure. My friend, however, doesn't care for such . . . feminine things, so she'll have the milkshake." She shot a pointed look at Quinn, who tried to make herself invisible, but that was all for naught. Zia decided that Sally needed a major attitude adjustment, the sooner the better. So she made them their drinks in record time, served them, and let her creations do her job for her.

"You need to work on your image more if you ever want me to invite you to a party being held by the popular kids," Sally told Quinn casually, not seeing how shameful it was for her friend to bring it up in public.

"Like what?" Quinn asked.

"If you ever want to rise up the ranks, you've got to start with the little things, like getting rid of all that acne. It looks terrible," Sally pointed out. As she spoke, Quinn's face started clearing up. Soon, her face was completely clear of spots, while Sally's face was littered with pockmarks and zits and acne scars. But neither girl noticed, which was all part of Zia's plan.

"After you've got that under control, you should start getting used to makeup. Going all natural just doesn't work for you," Sally criticized. Now it was her wearing no makeup, while Quinn wore a little mascara, lipstick and her nails were done beautifully.

"Here's another good tip for you, stop stealing from your granny's closet. Wear clothes from this century, please!" Sally advised. Both girls' clothes changed and morphed into new, but very different outfits. Sally wore a blue 1D shirt with green and orange striped leggings, topped off with a ratty old pair of trainers. Quinn looked stunning in her new outfit of white jeans with a purple dress over it, and a pair of sandals with heels that looked new.

"Now I have to talk to you about your hair. You can't just brush it! It has to be styled, washed, the split ends will need to be trimmed . . . Basically, it has to be perfect," Sally nitpicked. Neither girl noticed how Quinn's hair was now the envy of girls anywhere, while Sally's hair was a tangled mess at best.

"Once that's done, you'll have to lose a lot of weight before you can ever get a date without being laughed at. Nobody will want you if you look like you spend your free time tasting everything the bakery has to offer," Sally told Quinn. As the now beautiful, curvy girl sobbed and ruined her mascara, she began to slim down. She went from being a wide-load to portly, then fat, chubby, healthy, and then curvy. Meanwhile, if you looked at Sally, you would be able to see where all Quinn's excess weight had ended up . . . and then some. Sally looked like she was going to break the chair she was sitting on, her porky body leaning over the table, which roared with relief when the two finally finished their orders, paid and left. As they walked, several wolf whistles were called from around the high street. Quinn didn't know that they were for her, but Sally was used to them, blowing kisses to the confused and sometimes disgusted boys. Both of them were still in the mindset that Sally was the dominant friend, and Quinn was the lackey. That all changed when Max walked up to them.

Everyone knew Max. He was the head of the wrestling team and helped out at the animal shelter. He was desirable, to say the least. Sally and Quinn stopped dead in their tracks when they saw him coming. What could he possibly want with them?

"Hello, ladies," he greeted. "Why, you look gorgeous, Sally. Did you dye your hair brown, because it looks perfect on you. Compliments the purple dress."

"What purple dress?" Sally asked, looking at Quinn to back her up. That's when they finally saw the transformation they'd undergone. Sally screamed with horror, while Quinn quietly basked in the glory of her new look. "Oh God, I look horrible!"

"Why do I have so much energy?" Quinn wondered aloud. "I feel like I could go shopping for ages!"

"I'm sorry if I caused any confusion. Maybe I should go," Max said, but Quinn grasped his arm.

"No, it's fine. I'd like to talk to you more, if you don't mind," Quinn smiled. "And by the way, I'm not Sally. My name is Quinn."

"So where's Sally?" Max asked, forcing Sally to raise a chubby hand.

"I'm right here," Sally said. Max did a double take.

"Sally? You look . . . different," he said. "What happened?"

"I don't know!" Sally screamed. "First I'm slim and gorgeous, now I'm wearing my granny's clothes and I'm super fat!" Pointing a now chubbier finger at Quinn, she screamed, "This is all your fault!"

"Me?" Quinn stammered, shocked.

"Yes, you!" Sally accused. "It's all your fault that I'm not hotter than you anymore because . . . oh, everyone knows that you were the ugly one and you're jealous of me!"

"If you can't think of a real reason why Quinn is to blame, then leave her alone!" Max defended, standing up for Quinn before she burst into tears. "Why are you so mean to her? I thought you were trying to make yourself look better by having her as a friend!"

"You think she was really my friend?" Sally scoffed. "I had her as a servant, a piece of decoration! I would never have her as a real friend!"

"I can't believe you're so mean!" Max exclaimed, putting an arm around Quinn. "It's OK, Quinn. How about you walk around with me for a while?"

"Thank you," Quinn told him. Sally stood on the sidelines, outraged that Quinn got someone who had desirable written all over him. But as she looked at her new self in a shop window, she realized that she wouldn't get anyone like that for quite some time.

Meanwhile, inside the café, Zia Minh sipped on a mango smoothie and smiled as Quinn and Max walked away together. The many similarities they shared would ensure a happy relationship. Zia's enchanted drinks that both girls had drunk had caused all Quinn's faults to reflect onto Sally and no longer apply to Quinn. Basically, there was a hypocrisy spell on their drinks that caused Sally to swap qualities with Quinn whenever Sally criticized Quinn. Sally would never bully anyone ever again.

Once summer ended and the two transformed girls had to go back to school, they got quite a reception. Neither girl was recognized until registration came, when they were forced to answer to their names. Quinn was the centre of attention, everyone wanting to know how she changed so much. Quinn played it cool, naming a random well-known diet as the reason for her sudden change. She made plenty of friends, moved up the ranks and became the new queen bee, encouraging inclusiveness instead of unattainable perfection.

Sally's demise was cheered throughout the school, most people fantasizing that her ego had become pure fat. Toasts were held in the name of karma, parties were thrown and music was played. Sally would try to hit back, but none of her insults hurt anyway. Everyone thought that she was just jealous. The worst part about it, in Sally's eyes, was the lack of attention. Nobody wanted to be near her now. Before, she had a steady stream of hot boys worshipping the ground she walked on, although some of them were keeping a good distance away after they heard of her heart of stone. But now she had no good looks to fall back on, she had nothing. Her heart of stone and her new appearance combined to make a girl that couldn't get a date if she paid them.

She still blamed Quinn for her appearance, although the more time went by, the less she remembered about the event. Soon, she forgot all about the mystical Miracle Milkshakes café.
