Originally a one-shot that I decided to add more to. This is set awhile after the movie, still in summer, and everything has gone on pretty much the same. I guess it's not really a spoiler for the movie, but some people may think it is. It all starts with Isabella having a dream...

Isabella was standing next to Phineas in a strange room she had never seen before, with all her other friends around them. Suddenly, out of nowhere, she kissed him, he smiled, and then there was a flash of light and-

Isabella woke with a start. She sat up in her bed and thought about her dream. Of course she had dreamed about kissing Phineas before, but never had the dream been so vivid. It was as if it had actually happened... She shook her head to clear it and jumped out of bed, quickly getting dressed and then running downstairs. Her mother was in the kitchen, making some toast.

"Good morning Isabella!" said her mother.

"Morning mom! I'm going over to see Phineas and Ferb, okay?" asked Isabella hopefully.

"Of course dear, just take some breakfast with you." Isabella's mother handed her a piece of toast, and then Isabella ran out the door and across the street, finishing her toast in a few bites. She stopped running when she got to the driveway, seeing Candace walking down it, looking very happy.

"Hi, Candace!"

"Hi, Isabella," replied Candace, "Can't talk right now, going to see Jeremy."

"Okay, see you later!" Isabella walked the rest of the way to the gate and opened it, seeing Phineas sitting alone under the tree, looking like he was thinking. He looked up when he saw Isabella.

"Hey Phineas," she said, "Whatcha doin'?"

"I'm trying to think of what to do, actually," he replied, "Ferb is at the dentist for the day, so it looks like it's just you and me! What do you want to do today?"

Isabella's eyes lit up. A whole day with only Phineas! It was a dream come true! And she had the perfect idea.

"Well, we could go to the park! There's supposed to be a lot of street performers there today!"

"Sounds like fun!"

At that moment, Phineas's mom, Linda, walked into the backyard with her purse over her shoulder.

"So what are you two up to today?" she asked.

"Isabella and I are going to the park to watch the street performers!" answered Phineas.

"Well, you two have a great time! I'll see you back here for dinner!"

"Bye!" said Phineas and Isabella at the same time. Once she was gone, Phineas stood up.

"Come on, let's go! Hey, where's Perry?"

About twenty minutes later, Phineas and Isabella arrived at the park. All around them, there were musicians, dancers, jugglers, acrobats, and about a million other performers.

"So," started Phineas, "where do you want to go first?"

"Why don't we get some ice cream and walk around a bit and find an act to watch?" answered Isabella.

"Okay!"

The two of them walked over to an ice cream stand and bought two chocolate cones, and then walked through the park until they found a magician doing some magic tricks. They sat down to watch, Isabella content to simply be sitting next to Phineas.

After a few minutes, Isabella started thinking about her dream. Phineas had been so happy when she kissed him, but then she had woken up, and she never even got to see anymore of his reaction. She wondered what he would have really done if she had kissed him. She glanced over at Phineas, who was happily watching the magic show. Her heart started racing. It was hard enough to hide her feelings with their friends around. With just the two of them, it was all Isabella could do to not wrap her arms around him and kiss him for real. The only problem was she didn't know what he'd say. What if he didn't like her back, and it ruined their friendship?

"So, Phineas, are you having fun yet?" she asked nervously.

"Yeah, this magician is great! I especially liked it when he made that kid disappear and then reappear again behind us! Of course, Ferb and I could do that for real, and it would only take some simple engineering and maybe a particle accelerator, and then we could-

"Phineas there's something I need to tell you!" interrupted Isabella. Phineas turned to look at her and smiled.

"Sure Isabella, what is it?"

"Well, you see, there's something I've been meaning to tell you for awhile. I-"

Isabella was suddenly cut off by the magician coming up to them and pulling them both to their feet.

"Would you two like to help me with my next trick?" he asked, oblivious to the fact that he had just interrupted Isabella's confession to Phineas.

"That would be great!" replied Phineas. The magician led the two of them to the stage, where he then handed them both a glass of clear liquid.

"Alright, on the count of three, I want each of you to pour the contents of your glass onto the others head," instructed the magician, "and don't worry, you won't get wet. One, two, three!"

Both Phineas and Isabella poured their glasses on one another heads as the magician had said. There was a puff of smoke, and when it cleared, the rest of the crowd gasped. The magician handed them each a mirror, and Isabella also gasped when she saw that her hair had turned orange like Phineas's. When she looked at him, his hair was now black as hers had been.

"Cool!" Phineas exclaimed, while Isabella laughed. The magician then grabbed his wand and and started saying his magic words.

"Abracadabra, alakazam! Phineas and Isabella, presto chango!" There was another puff of smoke, and when it cleared, Isabella looked into her mirror again to find that her hair was back to normal, and so was Phineas's.

"That was so cool!" she exclaimed. The magician thanked them for their help, and the two of them went to find another performer to watch.

"Hey Phineas, how do you think he knew our names?"

After another minute, they came across an acrobat who was doing stunts on a skateboard. The two of them sat down to watch, and Isabella was feeling kind of sad that she had gotten interrupted right when she had decided to tell Phineas how she felt. Now she sat quietly as the performer did hand stands and flips while on a skateboard. Isabella, still feeling slightly brave, decided to make a move to see what Phineas's reaction would be. She shyly slid her hand over to Phineas's, and held it in hers. Phineas looked over at her and smiled, and then looked back to the performer, not taking his hand away. Isabella's heart soared, and she had to try hard to stop herself from fainting.

"Thanks for suggesting we come here Isabella, I had a lot of fun!"

A few hours later, Phineas and Isabella sat on a bench in the park, just talking. After seeing a few more performers, they had gone to the little market that had been set up. Isabella had seen this beautiful heart shaped necklace, and Phineas had decided to buy it for her. She now wore it around her neck, it meaning more to her than Phineas had yet to know.

"I had fun too! Thanks again for the necklace." she said back.

"No problem. We should hang out like this more often!"

"Yes, yes we should." Isabella smiled very happily.

"It's almost time for dinner, we should probably be heading back home now." said Phineas. Isabella sighed. Phineas was right, they should be getting back. They both stood up, and started walking back to their houses. When they arrived, they saw Linda pulling the car into the driveway.

"Hi mom!"

"Hi kids! Did you two have fun?"

"Yeah, it was great!" replied Phineas, "we saw a magician, and an acrobat, and a juggler, and a ton more cool things!"

"I'm glad you had a good time. Your sister is staying at Stacy's tonight, so it's just us until your father brings Ferb home from the dentist later. Isabella, would you like to stay for dinner?"

"Okay, thanks! I'll go ask my mom right now!" Isabella quickly went across the street to her house to ask. Her mom said yes, so she went back to Phineas's house to find him in the backyard again.

"Dinner's gonna be ready in half an hour, so we can hang out back here until it is, okay?" said Phineas.

"Okay!"

The two of them sat under the tree, not saying anything until Phineas remembered something.

"Hey, didn't you have something you wanted to tell me earlier?" he asked her.

"Umm, yeah, I did." Isabella took a deep breath, and began. "Well, Phineas, you know we've been friends for a long time. And, we've had a lot of fun together, right?"

"Yeah, I love hanging out with you!"

"Well, what I'm trying to say is, we've been hanging out for so long, and after a while, I realized something..."

"What is it, Isabella?" Phineas slid his hand into hers, looking slightly concerned for her. Isabella smiled slightly, and then, at that moment, decided that there was no turning back now.

"I think this will explain it." and with that she leaned over and kissed him. Phineas's eyes bulged, and when Isabella pulled back, he smiled wide.

"Isabella, I, you, I mean, wow!" Phineas was practically speechless.

"Phineas, I've liked you for a long time but I didn't know how to tell you," said Isabella, the words tumbling out of her mouth, "I didn't know if you felt the same way so I didn't want to do or say anything in case you didn't, because I didn't want to ruin our friendship. And then I tried to ask you to see a movie, but you and Ferb got fused together, and I asked you to the girls choice dance but you thought I was asking both of you, and than I dreamed that this happened but I still didn't know how you'd feel, so I was going to tell you earlier, but that magician turned my hair orange, and I-"

Isabella cut off to find Phineas kissing her again. She closed her eyes to savor this moment. When Phineas pulled away he hugged her, and Isabella felt as if there was nothing else in the world but the two of them.

"Isabella, I can't believe that you feel this way too! I've always liked you but I thought you wouldn't like me back so I distracted myself with all these inventions, and I didn't even notice how you felt. I'm so sorry."

"Don't be Phineas! I never thought that this would actually happen!" The two of them pulled apart, but they still held hands, much to Isabella's delight.

"Promise from now on that we'll never try to hide our feelings again, okay?" she asked.

"Promise." The two of them smiled wide, and hugged once again, both happy to finally be able to be with one another. Just then, they heard a familiar clicking sound coming from behind them.

"Oh, there you are Perry! You'll never guess what happened today!"
