Summary: "I'm sorry I need to leave, but I think that we both need time, so I'm leaving for the city where I can forget it all." Only one problem, what city is that? And Phineas has to find her, or lose her forever.

A/N: Alright, so I was reading some PnF fanfiction stories and I reread my "It's A Wild Cruise Ride" story, and as a result, this happens. ANOTHER STORY!

Chapter 1: The Letter

Early this morning, twelve year old Isabella Garcia-Shapiro went missing from her home in southern downtown Danville of the greater Tri-State Area. Wearing her signature outfit, she has all but disappeared without a trace, and the only thing found at the scene of her disappearance, A.K.A. her bedroom, was a Chrysanthemum flower... Local Authorities are completely baffled, and the local Fireside Troop 46231 has vowed to never stop searching for her until she is found. Mayor Roger Doofenshmirtz himself has dedicated a police task force to find the young Garcia-Shapiro. Her family's neighbors, the Flynn-Fletcher family says that Isabella always comes over at the same time every day, and only when she never came did they wonder and find her gone. If anybody has any news leading to finding of young Isabella Garcia-Shapiro, the police are urging you to call the toll free number at the bottom of the screen. More news after the break.

With a sigh, Phineas turned off the power to the TV. He knew what happened. Nobody else did. Nobody else would. Isabella hadn't been kidnapped; she had left on her own... Fleeing Danville... No... She wasn't fleeing Danville... She was leaving from him. For him...

Phineas remembered waking up this morning and finding a letter on his bedside table... Thinking it was a letter he could read later, he skipped reading it in favor getting started... When Isabella never showed up and the Fireside Girls hadn't seen her, Phineas had gone over to the Garcia-Shapiro's to find Isabella's room a complete mess.

Immediately Phineas had gone back to his room and opened the letter, fearing the worst.

Dear Phineas,
While you may be reading this message, I am leaving Danville.

You have proved to me yesterday that you value the inventions that you make over the friendship that we have... One we had even before we met Baljeet, or Buford, or Ferb...

So, I've decided to give you time to think about this friendship.

I'm so sorry that I need to leave, but I think that we both need time, so I'm leaving for the city where I can forget everything.

All of my memories of and with you are in this envelope. I'm giving myself fake memories and living elsewhere.

If you truly value our friendship over your inventions, then you should come and seek me out.

If you come to seek me out, you must convince me to come back with you and be able to get my memories back.

If you decide to let me go. Get rid of the capsule that has my memories in it. Get rid of it and let me go...

Phineas had desperately hoped that there was some clue that he could use to find her, but everything else was blurred out by tear drops. Not Isabella's... They were his own, on the possibility of losing Isabella forever.
