Okay I should be working on some of my other stories, but I couldn't help myself. I had to write this! It was going to be a oneshot, then it changed to a twoshot, now quite possibly it's going to be a four chapter story. The song 'Are you Gonna Kiss Me or Not' by Thompson Square inspired me to do so. The song will come into play in the next chapter. And of course, this is a Phinbella story. :) Okay, guess that's it for now. Please enjoy!

Disclaimer: I don't own Phineas and Ferb!

"Hey Phineas! Whatcha doing?"

Yes, you guessed it. That voice was none other than Isabella Garcia-Shapiro. The young girl was dressed in her usual pink dress with a matching pink bow and shoes. She was making her usual trip over to the Flynn/Fletcher household.

Her visits always led to her asking her punch line question, then she'll get her answer, then it will follow with her assisting the young boy that she secretly adores and then lastly, she'll go home.

But today was different.

Today was the day that she was going to ask if Phineas Flynn would spend some time with her alone. This time she would succeed, unlike the time she asked him out to the movies. Not soon after she got Phineas to say yes, and after he told his brother that he'd see him at home later… poof! Somehow both brothers were combined into one. That was the most bizarre times she's ever spent with the both of them. To this day, she doesn't know how they ever separated.

But never mind all that… this time was going to be different. She's just going to tell him that she wanted to spend time with him, and him alone. No offence to Ferb, of course.

So now, we go back to when she asks her most famous question,

"Hey, Phineas! Whatcha doing?"

Phineas and Ferb were both just relaxing next to the tree. Very odd considering these two brothers are almost always doing something cool and interesting.

Phineas smiled at her, "Hi, Isabella! Ferb and I are actually just relaxing today."

Isabella frowned, "Why? Are you two feeling all right? You guys never waste a nice summer day like this."

"No, no, we're fine… we had a late night cleaning up the last project we did yesterday, so we're just taking it easy today."

"Oh, okay that's cool," Isabella started tugging on the collar of her blouse, "Um, Phineas?"

"Yeah…?"

"I was wondering… if you're not doing anything tonight, would you like to come over to my house and watch a movie? Just the two of us?"

"Just the two of us? What about Ferb?"

Isabella's heart dropped, "I just thought… that it would be nice if you and I spent some time together… but if you don't want to-"

"On no, it's not that at all," Phineas looked towards his stepbrother, "would you mind, Ferb? Don't want you to feel left out."

Ferb just shook his head.

Phineas smiled, "I take it that he doesn't mind. Okay, Isabella I'll see you later tonight then. Is seven alright?"

Isabella had a hard time trying to contain her excitement, "That's fine, Phineas. I'll see you later then. Alright, then… I should go. Bye guys!"

"Bye, Isabella!"

Isabella opened the gate back up and exited through it. She hurried home with a little skip in her step. She couldn't believe it! Everything went so well and tonight she'll finally be able to spend some alone time with Phineas.

Upon reaching home, she called out to her mother,

"Mom! Mom, come quick!"

Her mother, Vivian came running downstairs,

"Si, si Izzy! What is wrong, are you hurt?"

Isabella shook her head, "No, mom I'm fine. I'm better then fine, I'm great!"

"Ah, I'll take it that Phineas said yes about your date?"

"Mom, it's not a date! We're just spending time together… without Ferb. And yes, he did say yes!"

"Oh, Izzy I'm so happy for you. I can't believe that my little girl is growing up so fast. Here you are, ten years old and you're having you crush over for a movie. Oi, where does the time go?"

"I'm not that grown up, mom… oh, I should go and get ready! Phineas is going to be here in five hours!"

With that, Isabella darted up the stairs into her room. Vivian shook her head,

"Ah, young love…"

Right after Isabella left Phineas couldn't help but notice the weird look his brother was giving him.

"What?" Phineas asked,

Ferb just grinned and stood up.

"What's wrong," Phineas asked, "Are you offended that me and Isabella are going to spend some time without you? Because I can call and cancel if you feel that way."

Ferb sighed and started toying with his wrench.

Phineas stood up and stood next to his brother "Come on, Ferb. For once, talk to me. What's with that look?"

Ferb rolled his eyes, "You're so oblivious, brother."

"I'm oblivious? Of what?"

"To the fact that you're oblivious…"

"I still don't get what you're saying. What did I do that makes me oblivious?"

Ferb chucked, "Phineas there's a reason that, Isabella want's to see you alone tonight."

"There is?"

"Yes… yes there is, and I'm not sure that you're worthy enough to know."

Phineas frowned, "Her come on now, Ferb. I can't be all that bad, can it?"

"You haven't noticed for years now… but I have…"

"What haven't I noticed?"

Ferb didn't answer.

"Oh no you don't," Phineas spoke, "you can't just go silent on me now."

"Here's some hints… wanting to go alone with you to the movies, being in the city of love, stranded on a island with a nice sunset, day dreamy looks whenever she sees you…"

Phineas was clearly confused, "I don't… quite understand…?

Ferb groaned, "Do I need to spell it out for you? It's Isabella!"

"Isabella, what about her?"

Ferb grabbed his brother's shoulders, "SHE wanted to see a movie with you, and only you, remember? SHE was miserable when we left Paris, remember? SHE was crying on that island, remember? And SHE looks at you like she has for a few years now!"

"Wait… Isabella? You're talking about, Isabella?"

"Yes… yes I'm talking about, Isabella. Phineas, Isabella… has a crush on you."

For once in his life, Phineas was speechless. His best friend in the whole wide world… had a crush on him? How's that possible? He's good at reading people, right? He should know when-

Then it hit him. A few weeks ago when Isabella was looking forward to seeing that movie with just him, and then something hit him and Ferb and combined them together. That confused and disappointed look she gave him. Then there was that time when they were landed in Paris to refuel their flying machine during the middle of summer. For some reason she seemed very distressed but he didn't even bother to ask her why. Finally there was that island… he was so busy freaking out and trying to win a stupid bet; he didn't even take the time to find out why she seemed so sad.

All this time, it was all because she liked him. Scratch that, she LIKE liked him. How could he be so naïve and stupid?

Phineas took a couple steps back, "I can't believe it… all this time that I've been spending with her. She was trying to get my attention and I was completely blowing her off. I can't believe that I've been so… blind."

Ferb sighed, "At last, you've come to realize her true feelings. Now… the question is, how do you feel about her?"

That was a good question. How does Phineas feel about his best friend? He likes her, of course… but could he possibly feel the same way about her, like she does him?

When he started thinking about her, his cheeks grew warm and he started getting little flutters in his stomach. Could this also be him liking her as well? Looking at Ferb, he probably wanted to know as well.

Phineas gulped, "I… I think I do, Ferb. I mean, I've always liked her, and… I think I could begin to soon really like her as well."

Ferb smiled, "You may think that… but I can see in your eyes that you already do."

Phineas went to reply, but Ferb shook his head, "Don't even try and argue… besides, you should probably start getting ready. You're going to need all the time you can get."

Phineas chuckled, "Yeah, I guess you're right."
