This fanfic is for Perryshmirtz fans to enjoy! It was greatly inspired by Demidae's fanart of the couple entitled "Fanart50 2 They'll Never Know". I don't have credit of the picture and I hope I cause no offense.
It had been nearly 5 years since Phineas and Ferb's Summer Vacation.
In year 3, the family had moved away, leaving their pet platypus behind. Perry lived in the Owca base and still fought Dr. Doofenshmirtz.
In year 4, Perry had been transformed into a human by Doofenshmirtz where her gender was made known to the confused doctor.
By year 5, the duo had fallen in love. They kept it secret to not be torn apart by Owca and Lovemuffin. Battles were small and easily decided to let Perry win. Days off were spent discreetly seeing one another. Walks in the park, playing on the beach, going over to "keep an eye" on the other. No one had the slightest clue. They assumed it was part of the more informal side of their "frenemy" relationship. Till one day.
"Carl! Where's Agent P? She should be back by now!", Monogram ordered.
"I'm afraid I'm not sure, Sir.", Carl said with a shrug. "It IS getting pretty late though. Do you want me to call her in?"
"No. I'll do it myself.", Monogram said. "That woman's been arriving later and later by the mission."
Where was Perry? Perry was still at the DEI. With the lights turned low, Perry was still captured in one last embrace as the couple said their goodbye.
"Nnn... No. Heinz, really. I have to go.", Perry said, pulling away from their kiss.
"Come on, Perry, not yet. Please?", Heinz begged, pulling her closer.
Her watch began to beep, meaning Major Monogram was trying to contact her.
"No, Heinz.", Perry said, backing up out of his arms now. "I'm sorry but you know I have to go."
"Come on, Perry. Please don't leave me alone again.", Heinz said in a half-hearted joke.
After all he was normally very alone. Ever since Perry fell in love with him, he's only been physically alone.
"No, Heinz I have to.", Perry said with a small smile. "Besides, you know I-"
"No. Perry.", Heinz said, with a smile of his own. He reached into his pocket and pulled out a small box which he opened up to reveal a ring with amethyst and sapphire jewels. "You don't have to...unless you want to."
Perry stared in shock at the ring, understanding what he was saying. She gave a smile and Heinz could feel his heart swell with joy.
"AGENT P!", Monogram's voice cut through the sweet silence they shared, though he wasn't heard.
"Of course.", Perry whispered to him, taking the ring.
"Thank you.", he mouthed.
She gave a nod and turned to her watch to say, "I-I'm sorry, Sir. Yes?"
"Where are you!? Do you know what time it is?!"
"Y-Yes Sir. I'm sorry. I was a little caught up in Doof's trap.", she said, blushing a bit.
"Well hurry up! We need you in before we lock the doors.", Monogram barked.
"Yes, Sir.", she saluted, he signed off.
She turned one last time to her fiance and with a hug, a kiss, a goodbye, and a promise, she left him for what could possibly be the last time.
