Throughout the entire beginning credits, and advertisements of the movie, Isabella thought of ways to get Phineas' attention.

She was pretty sure she already had caught at least a little, as he had been stuttering, and wasn't able to concentrate when she sat close to, or leaned against him earlier today...so why not have his full attention?
Besides, no one else was around to interrupt them so this was perfect.

Isabella slowly scooted closer towards Phineas on the couch, bit by bit, so he wouldn't notice too much, and by the time the actual movie had started, there was only an inch of space between the two, which Isabella wanted to get rid of completely, but she didn't want her love interest to move away, or ask what she was doing, so she restrained herself.

About 5 minutes into the stumpleberryfinkbat (is that how it's spelled? I don't know) movie Phineas started to say something to his friend.

"Don't you love thi-" He began as he turned his head towards Isabella, but stopped abruptly when their noses almost touched. "Whoa...I c-could've sworn there was at least 5 inches of space between us..." He finished, glancing down at the fabric of the couch which could barely be seen as Isabella was so close.

He couldn't understand why she seemed so...clingy...today, but he was starting to enjoy it, yet he wasn't sure why...

"Oh. Do you want me to move?" Isabella hoped, and pleaded silently in her head he would say no, and that he didn't mind being close to her, but deep down inside she knew it would never happen.

"No, no. I a-actually kind of...like it." Phineas sounded unsure of himself, like he didn't really know why, but Isabella ignored that, and only paid attention to the part when he said he liked it when she was close to him.

"Is that weird?" He added quickly turning to face her almost completely, but not bothering to pause the movie.

Isabella giggled, which she noticed made Phineas smile. "No, I dare say it's normal." She said, snuggling into him, and hugging his arm, closing the gap between the two.

Phineas stiffened at this, but slowly relaxed. "Um, okay..." He said nervously, turning back to the movie, but he couldn't concentrate on it anymore, with his best friend's super soft hair against the bare skin of his upper arm, and the fact that she was so close in general made every ounce of focus leave his head.

"Hey, where's Perry?" Phineas spoke up suddenly after a few minutes. "And Ferb...?" He added, looking around.
"I don't know..." Isabella shrugged, still hugging her friend's arm. "And I don't really care..." She wanted to add, but she didn't.

"Oh well." Phineas sighed, and looked back at the screen before moving his arm that his friend was hugging to around her shoulders.

Isabella grinned. "Hey...we're getting somewhere today..." She thought to herself as she pulled her legs up, tucking them under her, and snuggling into Phineas' chest.

She was already finding this movie a bit boring even though it barely started, but she didn't mind.
It gave her a chance to think about how she was going to take this a little farther...but she wasn't sure if she should push him, he already seemed out of his comfort zone, even though he was the one who had put his strong arm around her small shoulders.

"I-Isabella? Is there something wrong, o-or are you trying to tell me something, and I'm not catching on?" Phineas asked out of the blue.

This caught Isabella off guard, and he knew it. He didn't know how he knew...he just did.

Phineas guessed by the way that she looked at him suddenly, he had either said something wrong, or she simply wasn't prepared for that question, but he wasn't sure which one it was.

"Um...b-both, actually..." Isabella said looking at her hands. "I'm a little surprised that you caught on..." She mumbled, but Phineas heard her, and she knew it.

Phineas took the remote, and paused the movie before taking his arm from around Isabella's shoulders, and positioning himself so he was facing her completely.

"Caught onto what?" He asked his friend, confused as to what she meant.
"I'm surprised that you caught onto the fact that...I was trying to get your attention. Usually you never do, and keep on working on your inventions, and...whatever." Isabella said sadly as she looked up at her friend.

"But...why me? Why not...I don't know...Ferb?" Phineas asked.

He was missing it all.
All the clues, hints, and obvious reasons were there, but weren't registering, they were flying over his head.

"Because they aren't you, Phineas. Because I-" Isabella stopped, not knowing if she should continue, or if he would freak out, or say he doesn't like her back, but she decided it might just be worth it. "I like you." She whispered looking back down at her lap.

"Aw, I like you too Izzy." Phineas smiled, and watched as Isabella looked back up at him, and sighed sadly. "That's not what I meant, Phineas.
I...have a crush on you." Isabella said quietly.

Phineas didn't know what to say. He was confused, shocked, and angry...but at himself, how could he not have noticed?

'Isabella has a crush on me? But why?
Why would she have a crush on some weird triangle headed guy?' He asked himself that second question a million times. But each time it was left unanswered.

"B-but, why-when...what?" He managed to say, except it came out as a jumbled mess.

But then it hit him.

All those times she tried to find alone time with him, all those times she came over, and said her cute, flirty catchphrase, all those times she stared at him with a dreamy look in her eyes, all those times she had been trying to get his attention...and he had never noticed.

Phineas groaned, and put his head in his hands as Isabella watched him in agony.

What had she done? Did he hate her now? What did she do to him? Why did she convince herself this was a good idea? Why?

"I'm such an idiot...I'm sorry Isabella, I am so, so sorry." Phineas mumbled, shaking his head back, and forth.

Isabella was the one who didn't know what to say now. She didn't want to say it was okay, because it really wasn't, he hurt her tremendously for years, and years, but she didn't want to say it wasn't, then have to explain why. That would just make him feel even more horrible.

'Well, I forgive him right? At least he has the decency to feel bad about what he did even if he didn't know he did it.' Isabella thought to herself. So that's what she settled on, that's what she would say.

"I forgive you Phineas. Besides I probably wouldn't be able to stay upset at you for very long anyway." She giggled, which made Phineas bring his head out of his hands. "How long?" He asked seriously.

Isabella knew what he meant. He wanted to know how long she had liked him, but she felt like she couldn't tell him. "I...think it would be better if you didn't know...at the moment..." Isabella laughed nervously, but Phineas frowned. "That long huh?" He said before both of them fell silent for a few minutes.

Phineas felt confused.
Should he say he didn't know if he felt the same way? Or try, and make it up to her somehow, and not say anything about his feelings?

How did he feel about her anyway?
He never really thought of her as more than a friend...but those feelings he got when she was close to him...weren't those feelings you got when you liked someone or something?

"How do you feel when your close to me?" Phineas asked. "You know, physically." He added to clear up any possible confusion there might be.

Isabella blushed before answering, and fiddled with her fingers. "Well, um...usually I get butterflies in my stomach, and feel very happy, and all warm and fuzzy inside..." She explained blushing all the more.

'Why is he asking me this?' She thought to herself. 'I don't understand why he needs to know this, unless he was...trying to figure his or someone else's feelings out...' That made sense to Isabella, but he probably doesn't feel the same way right?

Phineas thought over Isabella's answer carefully. 'She just explained exactly how I feel, so does that mean...?' Phineas didn't try to deny it. If he ignored his feelings any longer, he was sure he would break Isabella's heart.

"Why do you ask that?" Isabella asked the young inventor. She was expecting an 'oh just wondering' kind of answer, but what she got was more unexpected than she could have ever imagined.

"I asked that because...I like you too."
