Summary
To my sister, assuming she finds this: PLEASE DON'T KILL ME! I saw the ship listed in the list of ships and was intrigued. I'm sorry.
To anyone confused: She and I know what I'm talking about. If she doesn't... Well, I'll survive for sure, unless I do something dumb and show her it. If she does... Well, I'll need to pray.

Summary
Throughout their nemesis-ship, there were five times Heinz realized that he loved Perry, only to convince himself that he shouldn't. At the same time, there were five times Perry realized that he loved Heinz, only to remind himself that he couldn't.

Summary
Or, In which a formerly well-respected scienterrorist is outed as a mutant and leaves adult society, adopts a blueblooded wriggler, and begins a heretical quadrant-smearing courtship with a lusus with rebellion espionage training who himself unwittingly adopts three orphaned children.
Contains graphic depictions of dismemberment, death, heretical relationships, anti-imperial sentiments, and a juvenile understanding of how the non-conciliatory quadrants work. Not suitable for trolls 6 sweeps and under.I found this buried in my Google docs from like 2017 and thought yall might enjoy it?

Summary
Believing that everything in his life could be fixed if he had only become class president in High School, Heinz Doofenshmirtz uses his past invention, the De-Age-inator, to become 18 years old again and quickly enrolls in Danville High. However, in the high school political arena, Doof faces fierce competition from his opponent, a girl named Candace Flynn, whom smells something fishy about the new "exchange student" and soon sets out to bust him!
When the two are paired as soccer rivals and then lab partners, though, their mutual understanding soon works against them and turns their fierce rivalry into something neither of them expected.
Heinz now has to ask himself if he's evil enough to take his daughter's friend to the prom before taking over the Tri-State area, while Candace has to answer, once she gets the evidence she craved, if she's prepared to bust someone she's fallen in love with? And if she'll really be okay this time when everything disappears.
It seems neither teenagehood nor middle agedness is all it's cracked up to be.
