A/N: My first Phineas and Ferb story! I've had half of this story written for almost two years, so I figured it was about time I uploaded it. Anyway, hope you like it. Oh- and I'll be updating this every Wednesday hopefully.

Feels weird writing a summer story when it snowed all day today.

Pairings: Mostly Phinbella and Canderemy , some Ferbnessa and... do Lynda and Lawrence have a ship name?

Disclaimer: If I owned Phineas and Ferb there'd be a new episode every day.

Parties, Proposals and Promises

The Plan

"Today was the best day ever, Ferb!"

"You have said that almost every day, every summer, every year since we were ten."

"You know what that means?" Phineas asked excitedly.

Ferb raised his eyebrows and Phineas translated that an admittance of no and a question of what.

"It means that our days keep getting better than the last. So by that logic it means tomorrow is going to be awesome!"

"More awesome than spending every hour possible with Isabella today? Because that's what you did."

"That- that wasn't the reason why it was awesome." Phineas responded in a dejected tone.

"And then a few more hours while you sunbathed at hers-"

"We weren't sunbathing, Ferb, we were just sat outside... in the sun."

Ferb rolled his eyes.

"With our clothes on." Phineas insisted. "Anyway, Isabella gave me a...a ...why are you raising your eyebrows Ferb?"

Ferb raises his eyebrows further.

"Dude! Come on! She gave me a great idea! We just finished school for the year, so why don't we throw a party and invite the whole gang? A sort of end of school- start of summer thing?" Phineas asked.

Ferb gave him a thumbs up and turned the lamp off beside his bed. Phineas agreed that perhaps they should discuss this at breakfast like they usually did, instead of right now and closed his eyes. They'd been sharing a room again for the past few nights and would be doing so for another few for the first time in three years, ever since Ferb moved out of their room and into Candace's at thirteen.

Candace was back from college- forever, and was home for a few nights before she could move into her own apartment with Jeremy.

Phineas smiled to himself. He loved having his brother back with him for a while. It wasn't that they spoke much during the night, but had they the need to it was easier than having to put on a head set or disturb their parents by wondering around at night.

He continued smiling and felt himself drifting, they'd had a long day of making the word 'impossible' feel embarrassed and the quiet chatter of Perry and the even quieter, slow breathing of Ferb was lulling him into a sound sleep.

That was until they heard a soft knock at the door. Ferb sat up immediately and turned his lamp on; Perry turned his head to look but really was just repositioning himself to get more comfortable, having had an equally busy day foiling his nemesis' plans.

Phineas pulled a shirt over his head as he got up to answer the door, and was surprised to see Jeremy stood there who had by no means grown as much as the brothers had over the past six years.

"Hey big guy. What's up?" Phineas asked him.

"I really need your help guys."

Phineas opened his door wider and let Jeremy in.

"What can we do for you?" Phineas asked as Jeremy closed the door behind him.

"Your parents and I are planning on having a party tomorrow. "

"How serendipitous, we were just discussing having a party as well." Phineas said and Ferb nodded. "What's the party for?"

"Um... well..." Jeremy quickly opened the door a crack and peered out into the dark, empty hallway. Satisfied, he shut the door again and turned back to the boys and platypus and took a deep breath. "I'm proposing to Candace." He told them.

Both boys immediately glared at him and this was definitely not the reaction he had expected from them.

They stayed like that for a few more seconds before breaking out into broad grins.

"It's ok. We accept too."

"You accept?" Jeremy asked.

"We assume you asked Mom and Dad first. It's ok, we like you too so we'll help."

Jeremy didn't exactly know what was going on but understood the 'we'll help' part and smiled gratefully.

"I remember you guys can pull off some great and well, lets be honest, crazy stuff-"

The two boys nodded.

"-And I was really hoping you'd help out- tomorrow."

Phineas and Ferb looked at each other.

"We usually plan at breakfast. And luckily you already know the whole gang." Phineas said excitedly.

"The 'whole gang'? No, I don't want it to be a big event; you know what she's like. She'll try and bust someone or arrange it herself and I want it to be a surprise. Do you think there's a way we can distract her for the day?" Jeremy asked.

Phineas snapped his fingers. "We'll ask the girls to help out! I'll give Isabella a ring and see what the fireside girls are doing tomorrow and Isabella can distract Candace, because they knew each other the most. They can do... something that... girls... do?"

Phineas and Jeremy both looked towards Ferb who looked thoughtful for a moment before shrugging.

"Isabella will think of something." Phineas assured and picked up his phone to call her.

The three of them waited and listened to the phone ring and cut off. Phineas cancelled and then tried calling again, twice.

"She's not picking up. Why isn't she picking up?" Phineas asked no one in particular and began pacing his room.

"Ferb, I'm going to have to go over there."

Ferb raised his eyebrows and Phineas' shoulders slumped in agreement.

"You're right, it is too late to just pop round. Mrs Garcia-Shapiro will be asleep by now so I'll have to go straight to her window."

"Is that a good idea?" Jeremy asked.

Phineas and Ferb looked at him incredulously. "This is for your proposal, Jeremy."

Jeremy looked taken aback for a moment and then nodded. "I'll just... I'll go back to Candace now. I don't know what you're doing or where you're about to go if your parents ask." He said and left quietly after Phineas thanked him.

"How am I going to get to her room though? I can't use the car because it's too loud and I don't have enough time to build something that would let me levitate or reach high enough." He said with frustration and checked his phone again. "Why isn't she picking up her phone? I can't even teleport there because she might not be decent or be so surprised that she screams and wakes up the whole tri state area."

"You could always use a ladder." Ferb pointed out.

Phineas looked at his brother in amazement and felt a hysterical laugh almost escape.

"You realise we've got to a stage now where I think of flying to her room before I think of a ladder?"

Ferb smirked and nodded when Phineas said he'd be back in a minute.

"Oh, and don't tell Mom and Dad I've gone, who knows what they might think?" Phineas chuckled.

"Why?" Ferb asked, "What are you thinking?"

Phineas blushed. "Nothing!" He said quickly. "Just tell them a lie if they come in for some reason."

Phineas pulled some trainers on and then exited his room, closing his door behind him quietly. He listened for a minute outside his parents' room and heard his Dad's snoring, and heard Jeremy whispering to Candace that he'd just been to the bathroom from outside Ferb's room, so he crept downstairs and went into the garage as quietly as he could. He flicked the light on and found the ladders immediately. He had to walk it back through the house because the garage door opening would definitely wake everyone.

It felt like taking every corner and avoiding every light fitting was taking forever. He slipped out the front door into the night and ran across the street, not being as careful about the noise he made now. He walked round the back of the Garcia-Shapiro residence and found Isabella's window.

The fact that her light was still on confused him. If she was awake why wasn't she answering her phone? She'd definitely had it when he'd last seen her that day, and it was ringing so the battery was fine. Phineas couldn't think of an answer as he placed the ladder against the wall beneath her window and shook it firmly to assure its sturdiness.

Before he climbed it, he figured he'd try the old 'throw stones at her window' bit, to see if she was actually in there. After he'd thrown three and seen no movement he decided she must not be, and decided to climb the ladders just to make sure.

He began climbing and thought for the first time what if she was asleep? What if she'd left her phone on silent and had fallen asleep reading and just not turned her light off? He realised he didn't know her usual bedtime antics and immediately threw that from his mind. He should not be thinking about that. Especially when he was two stories above ground.

He got to her window and peered in. She was awake all right. She was walking around her room and wait- she wasn't walking, she was dancing. He stared at her and couldn't for the life of him look away.

She had her eyes closed and was literally bouncing around her room with earphones in. He crouched slightly when he saw her turn and almost slipped when he tried to grab the ladder because his palms were suddenly sweating. He wiped them on his jeans one at time and wondered what on earth he was doing. Why was he hiding? He'd come here with the sole purpose to get her attention... not watch and then hide when she almost saw him like some creep.

All of a sudden the window above him slid open and her head popped out. Their faces were almost touching and Phineas gulped.

"Hey Phineas, watcha doing?"

So... Hope you liked it!

Anyway! Drop a review if you want, I'd love to know how I've done. See you guys next Wednesday!
