A/N:

HOLY CRAP! 47 REVIEWS! I'll be honest, I started another story on a different account, and I completely forgot about this one. I'm so so so so so sorry! I promise I'll try to update more! And just in case you didn't read the other authors note that said this, I will be writing two stories. One Phinbella and the second Ferbella. This will be the Phinbella one. I think this will either be the last, or second to last not very long. I don't really have any other ideas on what to do with the zsory. If you have some, though, please please please review or pm me! Thanks for being so supportive, and without further ado…. Enjoy chapter 3 :)

p.s. I know in chapter 1, it said she was 14 but they are all actually 15.

Chapter 3: I freaking love you

"You promise he won't be there?" Isabella asked, sitting on her bed. She was talking on the phone with Ferb, a rare occurrence, seeing as he didn't talk very much.

"Yes. He is out with dad getting new shoes. He wrecked his other pair building that giant skateboard park last week." He said his British accent even more obvious over the phone.

"Fine. I'll be over in a few." She hung up the phone and sighed, falling backwards onto her bed. She had embarrassed herself so much in front of Phineas that morning. How could she ever face him again?

She sighed again, feeling sorry for herself. She had just embarrassed herself in front of the love of her life. She stood up and changed into her normal outfit. It had changed a little from wen she was 10. Her being 15 now, she had exchanged her dress for a white tank top and deep pink skirt that accentuated her curves and contrasted nicely with her hair, which was shiny and black and fell softly to her waist.

She studied her face for a moment. Pale skin, deep emerald eyes. Nothing to fuss over. She thought she was rather ugly, herself, but guessed she was probably just being stupid, considering guys tended to fall at her feet.

She walked slowly to Ferb's house, trying to avoid what she knew was inevitable. She had to talk to Ferb, she knew that, but she didn't want to. She had already embarrassed herself enough in front of Phineas for one day; she didn't really feel like talking about her feeling with his brother.

"Isabella." called a voice, stopping her before she got to the front door. She turned around towards the backyard fence, only to see boy peeking over it. She recognized the red hair, and turned to run.

Why would Ferb do this to me? She thought. I trusted him.

She underestimated how fast Phineas was, and gasped when his arms locked around her waist and stopped her from running back to the safety of her house. "Before you even think about blaming Ferb, let me explain." He panted, not loosening his hold on her. She blushed when she realized how close they were standing. She could smell his cologne. She nodded, signaling for him to go on.

"So, I know I reacted badly. I'm sorry." He started, looking nervous. "There's something I need to say, though. " he took a deep breath, then opened and closed his mouth a few times. "You know what? Screw talking. I'm gonna show you." He laughed and grabbed her hand and ran to the backyard, dragging me behind him.

"What are we doing?" Isabella laughed, panting as they stopped running. She turned to him, expecting an answer, but he was simply pointing to something behind her. She turned around to see the Secrets machine, gleaming in the sunlight. Tears immediately filled her eyes.

"Why are you doing this?" she cried, turning back to him. He looked surprised, and then lost. He tried to explain but she interrupted him, continuing with what she was saying. "I understand if you're not in love with me… but do you really need to tease me?" she asked, tears running down her cheeks. His expression clouded with confusement, but his eyes widened and he smiled when he realized what was going on.

He smiled once at her, before stepping into the machine, and turning it on. Isabella sighed, what was the point of this? All this was doing was embarrassing her even more. Why does she need to know his secret? Knowing him, it would be something stupid, like stealing a candy bar or something.

She stood still, silently waiting, as the machine beeped and glowed.

"Phineas Flynn, 15 years old. Biggest secret: secretly in love with Isabella Garcia-Shapiro." The machine's monotone voice said. Her heart stopped for a moment as she processed the information. She couldn't understand it… Phineas loved her? No, it was too good to be true.

He stepped out of the machine and smiled at her. "So, what do you think of my secret?" he asked, blushing. She was still too dumbfounded to process the information, so she just stared for a few moments.

"…What does it mean?" she whispered, still thinking it was too good to be true. Phineas did a double-take at her answer, obviously not expecting her to ask that. He looked surprised for a moment. And stumbled over his words, but suddenly stopped.

He walked to Isabella and took her hands. "What does it mean? It means I freaking love you, Isabella!" he yelled, taking her by surprise. "I always have." He added softly, looking straight into her eyes. Isabella's eyes widened, and her brain raced to figure out how to form words.

Is he serious? She thought. I hope he is. If this is someone's idea of a cruel joke, well… lets just say they do not want to face me.

He must have noticed her confusion, because he abruptly grabbed her face in his hands and crashed his lips to hers. She gasped into his mouth and pulled him closer, hooking her arms around his neck. He backed her into the side of the house, putting his arms around her waist and pulling her closer, diminishing any space that was left between them. They pulled gently away, panting, and leaning their foreheads against each other.

"Do you get it now?" whispered Phineas, still slightly out of breath.

"Yes, Phineas, I get it." She giggled, pulling him into another kiss. "Hey Phineas?" she asked when they pulled away,

"Yah?"

"I love you too."
