(A/N) Here is a little something I've been dabbling with for a while. Hope you enjoy it:)
Disclaimer: I do not own Phineas and Ferb. Obviously.

Chapter 1

It was a typical day in Danville. The sun was shining, the birds were chirping happily. What a shame we were returning to school today. Ferb and I were returning to Danville high today, after another summer vacation of jam packed adventure! It was such a shame to go back to school. We were all returning as seniors this year, but that didn't make things any better. Sure, we're nearly leaving, but we still have to go to school. If you ask me, it caps our imagination. And if you knew me, you'd know I have a lot of it. Just as we had got down the stairs, the doorbell rang.

"Isabella, I presume." Ferb winked at me and walked into the kitchen. I gave him a puzzled look.

"Why did you just wink at me, Ferb?" I asked him, confused. Ferb sighed and shook his head.

"Just answer the door, Phin" He grabbed three bowls from the cupboard and set them out on the table.

I shrugged, and opened the door. There, as Ferb had predicted, was Isabella. She had been my best friend for as long as I could remember.

"Hi, Phineas. Whatcha doin'?" She smiled sweetly at me, and my heart seemed to flutter. Funny, that has been happening a lot recently. Maybe it's just something everyone goes through once in their lives. 'I'll ask Ferb about it later.'

"Hey, Isabella." I gestured for her to come in. "New outfit I see" I nodded to her light pink crop top and her tight skinny jeans. She always changes her style every year, and she has never looked bad once. Every girl at school looked up to her as their style icon. And I could see why too. She always looked beautiful... 'Wait, where did that come from?' I mentally slapped myself.

"Hello? Phineas, anyone in there?" Isabella was waving her hands in front of my eyes. I must have been lost in thought.

"Sorry, Bella. I think I zoned out for a minute there. What'd you say?" She smiled at me.

"I said, yes. Thank you for noticing. And I see you haven't, Mr. Stripy-yellow-and-orange-sweater-and-blue-jeans."

"Hey, my style is amazing. I did once bring out a fashion line, remember" I gently pushed her and she laughed.

"Yes, I remember. I still think you can buy them actually." We started to walk towards the kitchen, and Ferb was waiting for us, after making the breakfast. He smiled as we approached the table.

"Hey Ferb! Mmm, smells delicious!" Isabella took the seat next to me. After we had finished up, there was a loud bang on the door.

"I'll get it." Isabella walked away from the table and opened the door, revealing Buford, but not Baljeet. "Where is Baljeet? Not like him to be late."

"The nerd got sick today. He sounded like he was going to cry when I was on the phone to him. Ha, he has to miss the first day; I bet he's driving himself crazy." Buford chuckled. Ferb greeted him with a fist-pound and I smiled at him.

"Ready to go then?" I asked them, dreading the rest of the day. We all got into the car and drove off to school.

"Bye-bye summer vacation." I sighed, as we turned into the school parking lot. "It was fun while it lasted." We got out of Buford's car, and we went to our lockers.

"How are you feeling?" Ferb put a hand on my shoulder. I had managed to survive through the first lesson, but I wasn't sure how much more I could manage. It would be days till I got to invent again, since Ferb and I weren't allowed to invent in the cafeteria anymore.

"I'll cope, I think. It's just the thought of not inventing. I mean, we won't even have time after school. First day back and I already have a project." I sighed, slumping down on a chair. Ferb took one of the available chairs next to me and lightly punched my arm, as a sign of support.

Isabella and Buford came into class, laughing at something. Over the years, Isabella and Buford had become increasingly close; they seemed to bond whenever me, Ferb and Baljeet would 'geek-out', as they called it. Our group had seemed to grow apart in a way, as Buford, Ferb and Isabella shared many classes, they were the main group of friends. Baljeet and I just seemed to tag along every now and again, but I didn't mind; when we were younger, I was always the centre of attention, so I guess it's fair on them. Everyone at school looked up to them, or-in Buford's case-feared them. Baljeet was considered the brainiac of the school, so he still had popularity, but probably for the wrong reason. I was the inventor; the one with the great ideas. I was great friends with everyone in the school, but Ferb was most defiantly considered the better half of 'Phineas and Ferb'.

"Hi, whatcha-doin'?" Isabella chirped.

"Hey, Isabella. Just thinking about how wonderful it is to be back here." I replied sarcastically. Isabella sat down next to me and put her head on my shoulder. Her hair started to tickle my chin and I felt a sort of fuzzy feeling in my stomach. 'I must be hungry' I thought about how I could use one of mom's snacks right about now. I missed being at home, it was so much better. I could invent and draw till my heart's content, but here, I'm trapped.

"Don't worry, Phineas. It'll be the end of the day before you know it!" Isabella reassured me sweetly.

"Yeah, dinner bell. Don't worry about it!" Buford took the available seat next to Ferb, and got his books out ready.

I sighed, "So, what were you two laughing about?" I turned and forced a smile for Isabella. But in all honesty, the smile didn't take much force to appear. I just always felt like smiling whenever I saw her, but I never knew why.

"What? Oh, just about how Baljeet is probably tearing his hair out! He will be soo worked up!" Isabella chuckled.

"He was probably pinned down to his bed this morning" Ferb smiled.

I felt a little bit sorry for Baljeet. School was his domain, and he loved the first day back. But I couldn't help envy him. Sure, he was sick, but he didn't have to go to school. I never did understand why he loved school so much.

Our teacher tapped on the board, alerting the class that the lesson had begun. Everyone fell into silence, as she spoke, "Students, we must welcome a new member to the class. Her name is Eve. Everyone best make her feel welcome." The new girl walked through the door, and smiled at everyone.

"Hi, I'm Eve. Nice to meet you!" Miss Gering pointed to an empty seat and Eve sat down. Then Miss Gering turned her attention to me.

"Isabella, does Phineas look like a headrest to you? Sit up properly girl, unless your head is falling off, it does not need supporting on his shoulder!"

Isabella shot up. I guess we had both forgotten her position, and now the entire class was staring at us. I looked down at my book, hoping no one could see me blushing. I heard Ferb and Buford sniggering next to us, so I gave Ferb a friendly hit on the arm.

"Ow." He whispered under his breath, whilst holding his arm.

"Now then, class. Time to learn the difference between script and transcript." Our teacher turned on the projector.

"We learnt this last year!" Jack shouted from the back of class.

Jack was the typical jock, every girl liked him, he was strong and, I say this in the nicest possible way, very stupid. He gave jocks everywhere a bad name. Everyone knew he had a huge crush on Isabella, but I didn't care about that really. I mean, I care but... let's just say that he was just a bad guy in general; I had a bad feeling about him.

"Not to my level you didn't! Now, turn to page 154 in your text books. And do it fast, we don't have all day!" She demanded.

Everyone sighed. If Baljeet was here, I'm sure he would too. I could tell that this year was going to be a long one.
