Isabella left Phineas and Ferb's backyard with a big fake smile on her face. When she got home, she couldn't take it anymore, she ran up to her room and started crying. She took a picture out of Phineas and looked a it.

"Why don't you ever notice me!" she asked the picture.

She turned on the radio and heard a song that she never heard...

It had a catchy tune, so she cranked the music a little higher.

MMMM better...MMMM better...
Absolutely no one that knows me better
No one that can make me feel sooo goooood

Those lines reminded her of Phineas, he knew her ever since she was 3 and every time he smiled, she would feel instantly better.

How did we stay so long together?
When everybody, everybody said we never would

To be fair, Phineas and her would best friend, the only reason why a lot of people didn't think they would become a couple was because of Phineas's obliviousness

And just when I, I start to think they're right
That love has died...

That's what she was thinking right now, it was true... she should give up.

There you go making my heart beat again,
Heart beat again,
Heart beat again

Yea... he really did, everytime he took her hand and complimented her, she felt butterflies in her stomach.

There you go making me feel like a kid
Won't you do it and do it one time?

With him, she never wanted to grow up, she wanted to stay with him and his fun inventions forever.

There you go pulling me right back in,
Right back in,
Right back in
And I know-oo I'm never letting this go-ooo

She would try to give up, but he would also make her feel better right after, making her love him. She would never stop.

I'm stuck on you
Whutooo whutooo
Stuck like glue
You and me baby we're stuck like glue

Whutooo whutooo
Stuck like glue
You and me baby we're stuck like glue

They were definitely stuck together, no one could tear them apart.

Some days I don't feel like trying
Some days you know I wanna just give up

ForIsabella, those days happened all of the time...

When it doesn't matter who's right, fight about it all night
Had enough

Sometimes she was mad at Phineas, but Phineas would never be mad at her... she knew he would never hurt her...

You give me that look
"I'm sorry baby let's make up"
You do that thing that makes me laugh
And just like that...

She didn't know what "that thing" was... maybe it was all of him...

There you go making my heart beat again,
Heart beat again,
Heart beat again
There you go making me feel like a kid
Won't you do it and do it one time
There you go pulling me right back in,
Right back in,
Right back in
And I know-oo I'm never letting this go-ooo

Isabella started to sing along...

I'm stuck on you
Whutooo whutooo
Stuck like glue
You and me baby we're stuck like glue
Whutooo whutooo
Stuck like glue
You and me baby were stuck like glue

Isabella loved this song, it went exactly with her feelings and emotions... she didn't feel so alone anymore...

Whutooo Whutoo

You almost stay out, too stuck together from the ATL
Whutooo Whutoo
Feeling kinda sick?
Just a spoon full of sugar make it better real quick

She did want some sugar... But she figured that that wasn't what the artist of the song meant.

I say
Whutooo Whutoo
Whatcha gonna do with that?
Whutooo Whutoo
Come on over here with that
Sugar sticky sweet stuff
Come on give me that stuff
Everybody wants some
Melodies that get stuck

Up in your head
Whutooo whutooo

This song was getting stuck in her head, but he liked it...

Up in your head
Whutooo whutooo

Up in your head
Whutooo whutooo

Up in your head
Whutooo whutooo
Whuthoo whutooo
Stuck like glue
You and me together, say, it's all I wanna do

I said

That was all she wanted to do, that's why she went to his house every morning to say "What'ya doin?"

There you go making my heart beat again,
Heart beat again,
Heart beat again
There you go making me feel like a kid
Won't you do it and do it one time
There you go pulling me right back in,
Right back in,
Right back in
And I know-oo I'm never letting this go-ooo

She sand louder

There you go making my heart beat again,
Heart beat again,
Heart beat again
There you go making me feel like a kid
Won't you do it and do it one time
There you go pulling me right back in,
Right back in,
Right back in
And I know-oo I'm never letting this go-ooo
I'm stuck on you

She started dancing

Whutooo whutooo
Stuck like glue
You and me baby we're stuck like glue
Whutooo whutooo
Stuck like glue
You and me baby were stuck like glue
Whutooo whutooo
Stuck like glue
You and me baby we're stuck like glue

Singing and dancing, with her hair brush instead of a microphone, she smiled as the song ended.

Then she heard a clap.

She tuned around, surprised, and saw Phineas in her open window.

"Wow! You sing really well!" Phineas said.

"Thanks..." Isabella replied blushing.

"Yea..." Phineas said, getting carried away...

"So Phineas," Isabella said, snapping Phineas out of his thoughts. "Why did you come?"

"Oh yea, I wanted to give you this..." He handed her a pink rose.

Isabella's mind was going crazy. Her face was as red as an apple, but as happy as a bird

"I have to go now!" Phineas said running down to his house. "It's Taco Night!"

Isabella waved goodbye to him and put the pink rose in a vase.

But right before she put it in, she found a small not attached to it. She opened it up.

Hi Isabella!

Happy The Day We First Met Anniversary!

At First I wanted to give you the "When I met you you were 3 and we were playing together in preschool" card...

But I wanted to make this special.

Because you're a very special girl, and I wouldn't have asked for a better friend...

You're beautiful in every single way.

I love the sound of your voice when you come into our backyard.

How you're so helpful and energetic.

I thought I would write it down because its easier to say on paper

(because we're best friends... or are we :) ?)

Don't be sad, stay smiling,

Love,

Phineas Flynn

Isabella could have screamed he huged the paper and the rose... That was the kind of thing that would send her right back into his arms.

"There you go making my heart beat again,
Heart beat again,
Heart beat again
There you go making me feel like a kid
Won't you do it and do it one time
There you go pulling me right back in,
Right back in,
Right back in
And I know-oo I'm never letting this go-ooo"
