Summary
Leave it to Ratio to take a sex call from his home office setup. Noise-canceling headset, 4k webcam and all? Aventurine should’ve figured.
“What is this, your remote lecture?”
Aventurine's work trip might be keeping him worlds apart from Ratio, but distance won't stop him from putting on a show.

Summary
“Aren’t you dating Dr. Ratio? Is it true that he’s a total weirdo?”
"We're not dating. It's… complicated."
March blinks, quiet for a split second before firing off at the speed of light again. “Oh, I know this one! You’re in a situationship!”
Aventurine's hit with the IPC's lightest slap on the wrist after his actions in Penacony: an excursion onboard the Astral Express. It's nothing he wants to deal with, but he ends up finding an unexpected friend in March– and a little more with Ratio.

Summary
“Math?” And a published academic journal, at that?
“Yes.” Ratio returns the book to his bag, carrying on, but Aventurine’s stuck on the fact that this is apparently what he does in his free time outside of composing music.
“…I thought you were a pianist.”
“I am a pianist.”
“But– math?” Even Aventurine doesn’t spend that much time thinking about math, and he spends twelve hours a day staring at financial models.
“Does it not occur to you that it's possible to have more than one interest?”
Aventurine lives the same week on repeat: eighty hours of his soul-sucking high finance job, then two nights of dancing off the stress to the beat of his favorite anonymous DJ. His move into a luxury apartment building brings him next door to Ratio, an esteemed classical composer with a love for piano. Eager to make a good impression, Aventurine keeps his clubbing habit under wraps — but he’s not the only one hiding secrets under strobe lights.

To Catch a Hunter by celadon_dreams for wabilution

Summary
Aventurine takes on the hunt of a lifetime.
"Bold of you to say, considering that I have you at a disadvantage. Shall I enlighten you?" says Ratio, baring his long, sharp fangs.
They're enough to intimidate anyone, even a seasoned hunter like Aventurine; he can't deny the stab of apprehension that runs through him at the mere sight. But he's a professional first and foremost — he can handle it. "Doctor Ratio," says Aventurine, nailing the metaphorical coffin shut. "That isn't a deterrent in the least."

Bookmarker's Notes
I can't say this was the only story that inspired me to become a writer, but it was at least one of them.
Rest well, author. I hope I'll make something for someone worth as much as nebulous has given to me.
