A/N: THANKYOUTHANKYOUTHANKYOUTHAN KYOU! bookwrm23, you have not only made me REALLY happy about my writing, but you have also allowed me to use my slightly weird but totally awesome (in my opinion) idea! Here it is, in answer to your challenge, PHINESSA in Summer Belongs to You!
Phineas hadn't known beautiful until he had seen that young woman fall onto the windshield. For the first time in his life, he could truthfully say that he had a crush on a girl. But, of course, Ferb had to go crushing his dreams. How could he possibly know this person? How did he know Vanessa, as he had called her. Some random teenaged girl lands on their airplane in the middle of Tokyo, and he knows her. Ferb knew everyone. EVERYONE!
Then he decided to speak up, "No matter where we go, Ferb knows everyone!" then, without even knowing, he said, "Even some hot girl falling out of the sky off the coast of Asia!" After seeing everyone look at him and blushing, he said, "I just said that aloud, didn't I?"
"Yes," answered Vanessa with a smile, "Yes you did." And when they got to Paris, they went off together, leaving Ferb and Isabella heartbroken.
A/N: Yeah, that's one of my favorite couples. It does have its drawbacks though, I mean, Ferb and Isabella probably wouldn't appreciate it. I kind of see it playing out as a Romeo & Juliet type story, you know, minus the death and stuff. Anyway, see you guys soon!
