"Ah! I give up."

As he stood right in front of the Amnesia-inator, the British boy went into a brief flashback, silently, about the day when he and his brother stumbled across Perry's underground lair. He made many attempts to tell Phineas that he didn't build the high-tech basement, but to no avail.

Originally, Ferb did it simply out of plain frustration, but now, in retrospect, he was pretty glad that he had concealed the truth from Phineas. Well, not really "concealed", it's just Ferb had been tired of being interrupted every time he tried to mention it, so he didn't bother anymore.

And thinking back, he couldn't help but blame himself. He shouldn't had even given that a single thought in the very first place; he had been caught up in the temptation without realizing what it might have been, had he succeeded.

In a few seconds, Ferb was awoken from his trance by a lovely voice, which he recognized instantly as Isabella's. Head up, he smirked at the hesitant intonation of the girl; obviously, she had wanted to kiss her crush without him having any knowledge about it for far too long, so what better time than this?

Just as Ferb was about to burst into chuckles at his brother's amusing reaction towards the kiss- the speechless boy looked completely stupefied, he was blinded by an intense white light.

The next day, Phineas woke up to the chatter of the platypus. He stretched a little as he said, "Good morning, buddy!" Having already woken up, Ferb tacitly greeted his stepbrother; yet when he moved his sight to their beloved pet, he was extremely shocked to find himself picturing Perry in a fedora. Something must have triggered it, he thought, but what can it be?

"Hey Ferb, do you remember what we did yesterday? 'Cause I have no idea."

Ferb closed his eyes, searching through his memory. Much to his surprise, he was able to recall the entire inter-dimensional adventure vividly, along with the epic fight against Second Dimension Dr. Doofenshmirtz, a tough and relentless battle which they won eventually. His knowledge of Perry being a secret agent must have somehow managed to allow his brain to preserve the previous day, the effects of the Amnesia-inator notwithstanding.

Ferb opened his eyes and gave Phineas a negative response, even though it was the opposite extreme of the truth. This piece of information was supposed to be hidden in the back of his mind, at least for now; should he let the cat out of the bag, it could bring major problem, not only to himself, his family, and his friends, but also, possibly, to the entire universe. The consequences could be destructive, perhaps even irreparable.

Hence it was decided. All of these ought to remain confidential; not even Perry or Phineas can know about it.

Before heading downstairs with Phineas, the British quickly wrote in his diary, careful not to allow anyone else to see the words, the platypus included:

Mystique and cuteness,secretive and glorious

He's never ever out of style

If you're in a trouble then shout out his name

And he shall be there in a while

Ain't gon' be prominent

But you're the dominant

Make me see clearly in the mist

Not obligatory

Never compulsory

But when I hear you growl,can't resist

He closed the diary and placed it in a rectangular box. He then locked up the box; since he was only one who knew the code, he was certain that nobody else would see the contents.

Phineas was sitting beside his stepbrother, who was trying to keep his nervousness under control. Staring into somewhere faraway, the British appears to be contemplating on what they should do, whereas unbeknownst to the other, he was avoiding eye contact partly because he was scared to give out a recent secret of his own; indubitably, that puts a significant amount of stress over the youngster.

Phineas started to speak,"It's really bizarre we can't remember what we'd done yesterday. Nevertheless, whatever had happened, whatever we'd experienced, strengthened our bond with Perry somehow, I suppose."

Ferb couldn't agree more, except that he actually knew exactly why since he remembered the event. Knowing he shouldn't give out any clue, Ferb faked a thoughtful expression, which fooled Phineas successfully.

A chatter was heard. Phineas was patting their platypus when inspiration struck.

"Ferb, I know what we're gonna do today!", shouted the boy excitedly, jumping to his feet. Perry anticipated, fearing that Phineas would propose any big idea that could possibly lead to his owners learning(or rather, remembering) his confidential double life. Perry was rarely this nervous around the boys, but there was no second chance should his cover be blown again.

Isabella walked right through the fence."Hey Phineas. Whatcha' doing?", she asked, with a sweet and innocent intonation. This usual act of the girl got Perry on his nerves; under the mindless facade was a platypus heart beating a hundred times faster than normal. And then, much to the platypus's relief, the young inventor replied," Hi Isabella. Ferb and I are just about to start building the largest water slide ever. Ferb?"

Said boy showed Phineas the blueprint.

"I'm pretty sure Perry would love this one, although he's likely to be unable to join us in the fun, just like he always does," Phineas said. For a brief moment, there was slight sentiment in his smile, but the only one who had noticed was Isabella, since she was practically gazing at the boy for all time."Well, he might get a chance to have one ride if he's back early," Phineas concluded optimistically, before Isabella could say anything.

Hiding behind the tree was the platypus, fedora on, ready to hop into his lair. He felt content for having such
caring owners, and he is never going to allow anyone to take them away. Phineas and Ferb will always be there for Perry the pet platypus; likewise, Perry the secret agent shall keep protecting them from any malice. He knew he'd have a vexatious time trying to maintain the cover for several days, yet with their love, he was pretty sure that everything's gonna turn out fine.

Perry swept his eyes around on his boys and Isabella for one last time, before stealthily slipping into the tube which leads underneath. Looks like the Amnesia-inator served its purpose perfectly, he thought, no sign of anyone remembering the inter-dimensional adventure and all the craziness yesterday. Great.

"Hey Ferb, did we order the parts earlier this morning?" The green-haired kid shook his head no. Phineas said," I'll do it right now then." And with that, he walked into the house, leaving his brother(actually it's stepbro) and Isabella in the backyard, both of which as jittery as possible, albeit Ferb didn't show it.

Candace walked into the living room to see her little brother on the phone. Within a second, she instinctively shouted,"Phineas! I don't know what you and Ferb are doing, but you two are gonna be so busted!"

Phineas winced at the clamorous and piercing scream."Pardon me." He turned to his sister and said calmly,"Hey Candace. Just ordering the parts for our project today."

"Who was that girl? Her voice made my eardrums hurt"asked the man on the other side.

"Oh, sorry about that, it's just our sister Candace trying to bust us again",
Phineas replied.

"Is she always like that?"

"Yeah. Literally every day whenever it's summertime. She's constantly trying to do that; her attempts are still futile by now, though."

"How could you handle it?"The man inquired, to which the boy answered,"Yes, it was a bit irritating at first, but we got used to it soon."

When Phineas walked out, he saw his friend Isabella only. He was about to speak when Baljeet and Buford got in. Strangely enough, the nerd did not come in dangling onto or enclosed in anything or anyone; instead, they both simply walked in."Hi Phineas and Isabella." Baljeet greeted.

Isabella gave them a curious look."What? Buford don't feel like bullying this morning, 'kay?"

Phineas said," Hi Baljeet and Buford. I just placed the order, so it should take seventeen minutes or so before we
get those stuff. In the meantime, how about we all think about this question: what did we do yesterday?"

Isabella was in a trance once again until she heard Buford's typical raspy voice,"Why are we doing this? Buford see absolutely no fun in this."

"Oh, you'll be surprised. Ferb and I woke up to find that we can't remember anything from the previous day. So you really gotta give it a try, you probably won't remember just like us, but maybe any of you will. Who knows?"

"You could just check out your diary, Phineas."suggested Baljeet.

"We were too tired to keep a diary."

"Yeah, I know. I mean, I know why. I'm exhausted to death when I was finally home last evening. However, come to think about it, I can remember nothing; furthermore, when I try to think about yesterday, my memory became completely blank."Isabella said.

Phineas said,"Me too. Exactly the same as you. Hey, where's Perry?"

Isabella thought, oh Phineas, you're so gorgeous. Yet, will you ever realize how deep my love toward you is?

Baljeet asked,"And where is Ferb?"

Phineas looked around, but didn't spot his stepbrother. Weird, he thought, usually he's around me. "Did you see him l-" He was interrupted by the rustle of the leaves, and then Ferb fell from the tree, landing on his feet."There you are,Ferb. It feels a little funny saying that to you, because usually I say that to Perry- in the end of the day, also."

Ferb blinked, but it's an unusually extraordinary blink even for his stepbro and friends; in fact, the motion was so mysterious that even Phineas failed to decipher it.

Deep within his mind, the British murmured somberly, I'm sorry.
