Unforgettable Love - A Phinabella Story

Taking place after the events of Phineas and Ferb: Across the 2nd Dimension, this story shows Phineas Flynn trying to figure out why he remembers a single clip from a time that he doesn't remember having. After curiosity hits him, he finds himself back in the 2nd Dimension, along with his best friend, Isabella.

I do not in any way, shape, or form, own Phineas and Ferb! just this storyline :)

Phineas and Ferb is owned by Dan Povenmire and Jeff "Swampy" Marsh!

PS- i'm not sure if this has been thought of already, but this is my original idea.
