A/N: Hello once again! Every time I try to write a multi-chapter story, I fail.. I bail. Everything like that. But I'm REALLY interested in writing this one and I am DETERMINED to finish it. Okay, let me explain a few things. This fanfiction is based on a roleplay that I've had with my best friend, Ashley. (Puffedwarrior on deviantART & Fanpop! Search her~! You won't regret it!) In our roleplays, they are already dating. And in this one, Ferb was off in Britain with his dad, Candace was off somewhere; probably with Jeremy, and Phineas' mom is probably out with Isabella's mom or something.. I have no idea, but Phineas and Isabella were the only ones home. XD Perry was off fighting Doof, most likely, but sorry.. There will be no cutaway scenes with them in this because well... They have nothing to do with this. Aaannnyyywwaaayyysss, there will be a lot of things in this story that happens, but I'm not giving anything away at all! So... here we go! Enjoy~! ^^

Fatal Flames

Isabella sighed happily, walking over to Phineas' house. Another day of my life... Another day with Phineas... Love it.. She peeked her head over the fence, smiling brightly.

"Hey, Phineas! What'cha doin'?"

Phineas was sitting there, engrossed in looking at a machine. This machine was supposed to be a mind reading machine, but it wasn't going too well.. The first time he tried it out, Isabella and him had switched bodies, but he fixed it by putting a reverse button on it. The last time he tried to fix it, they both went into his mind. That was really embarrassing for him. Without Ferb here, he was failing to complete this task. He didn't notice that Isabella was there. She looked at him, confusingly, walking over to the fence's door, walking straight in.

"Phineas?"

His eyes weren't taken off the invention, as he groaned loudly, but then jerked his head towards her.

"Oh! Isabella, I.. I'm just trying to fix this thing.. Why can't I get it right?"

Isabella walked over next to him, sitting down on the ground beside him, as she rested a hand on his shaking shoulder.

"Phineas... Why don't you stop trying to work on that thing before something really bad happens?"

Phineas looked at her and shook his head, frantically.

"I'm not doing that! This is something that you really wanted to do... I am determined to fix this!"

"Alright.. Whatever you say..."

Isabella looked at him, in doubt, biting her lip and looking at the invention. Phineas sat there for a while, resting his chin on his hand. After awhile, he groaned, laying back on the tree.

"I can't do this! Why can't I do this..?"

Phineas buried his head in his hand, obviously confused. Isabella just grabbed his chin and pulled his face up to where he looked at her, smiling at him sympathetically.

"Phineas... You can do this.. You can do anything. You just have to believe."

"Then why did you seem so negative about it before..?" Phineas hung his head low, looking down at the ground below him. Isabella shook her head and laid down on the ground, to where her head was where he was looking.

"I'm sorry. I didn't mean to, I just.. I don't know what came over me.. Forgive me?.. I really believe that you can do this.."

She smiled up at him. Suddenly, Phineas smiled, too, leaning his head down towards her, as he gave her a quick kiss on the forehead, then sat up. Isabella also rose herself up, scooting as close as she could next to him, as Phineas began to work on the machine.

A/N: Welp, thats it for the first chapter. Kind of short, isn't it? Oh well.. I'm sure the other ones are going to be way longer. It may not seem very interesting right now, but trust me... It starts getting juicy! Reviews are greatly appreciated. They make me SMILE! :D
