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.

Long-Distance Situationships: The Cutest Girl’s Guide to a Photo Finish by catboykitchen for ghostphone
Fandoms: 崩坏：星穹铁道 | Honkai: Star Rail (Video Game)

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.

Summary
“I don’t understand the appeal in me wearing this,” Ratio says– same with the lingerie, and the bunny suit, and his doctor’s uniform, and his lab PPE, and the… well, everything.
Unfortunately for him, Aventurine thinks it’s really hot for him to be naked in an apron right now, so he doesn’t care.
A simple recipe for Aventurine's satisfaction: Ratio, apron, floor, tits at the ready.

Summary
“Really, doctor? All this time, and you haven’t had a moment to yourself? Let yourself relive that last time together when you left bruises on my hips?”
“I didn’t say that.”
Aventurine's been gone too long. Ratio can't take it any longer.

Summary
In what’s definitely a pre-planned rational decision and not a drunken lovesick impulse, Aventurine fashions a message.
> I wanna confess to ratio 🫣 how should i do it?? I need hlep please thanks. asking for a friend btw 🥺💖
He looks it over for what’s maybe a third of a second, decides he’s done a great job, and promptly sends it to every lesbian he knows.
They’d never let him down. Problem solved.
Five times Aventurine enlists help to confess, and one time he doesn't need to.

Summary
Maybe it won’t be that bad, he tells himself.
He opens the package. It is that bad.
It is just past six on a weeknight evening, and Aventurine thought it important enough to disrupt Veritas’s post-work activities to call him over for a… bunny suit.
Aventurine gets Ratio a surprise present. It goes about as expected.

Summary
“Ratio?” he asks, stepping a bit closer. “It’s me, Aventurine. Are you… do you want to go home?”
At the mention of his name, Ratio stills, a light startle in his step as he turns to face Aventurine. He drops his hands, lacing them back together in front of him. He looks dazed, normal intensity lost from his eyes as they open glassy and vacant. They flex wide with recognition, but he doesn’t say anything.
Ratio goes quiet, and Aventurine doesn't know what to do.

Summary
Upon meeting Aventurine, Veritas is filled with a feeling he can't quite describe. He calls it hatred, but is that really what it is?

Summary
This is probably his fault. There’s no other explanation for how it had all been very normal until a horrible high-pitched sound rang through the air with a blinding flash and he’d found himself sitting somewhere completely different once he’d blinked back to reality.
As it turns out, wishful thinking tends to make itself dangerous when you have a lucky streak.
Aventurine and Ratio get body swapped into Kaveh and Alhaitham's bodies. It takes some vulnerability to find a way out.

Summary
Random guy, who for some reason looks like a purple version of Alhaitham with worse fashion sense, huffs in a very arrogant, very Alhaitham-like manner. “Well, this is interesting,” he says, crossing his arms and looking around.
Kaveh squints his eyes. “Hey, um,” he asks, “what the fuck?”
Kaveh and Alhaitham get body swapped into Aventurine and Ratio's bodies. It's not their fault, but they have to wait it out until it's solved.

Summary
Sunday turns around, movement of his silhouette barely visible as Veritas’s eyes adjust to the complete darkness. The speakers crackle with static and flare out as his feet click still into the center of the room. Pain reverberates through Veritas’s head, but he doesn’t dare wince.
“You’ve returned."
Ratio and Sunday watch the finale of Aventurine's performance. Things get a little more interesting after the curtain call.

Who let you fish in troubled waters? by catboykitchen
Fandoms: 崩坏：星穹铁道 | Honkai: Star Rail (Video Game)

Tags
Summary
“Aventurine,” he asks, because Aventurine had asked him to ask him, so thus he must ask, “do you have any threes?”
“Hmm… nope! Go fish.”
Veritas draws a card. He turns to Boothill, expecting his turn to be over, but Aventurine pulls him back with a hand to his wrist.
“Okay, now strip.”
Aventurine sets up a game of cards. Ratio isn't happy about it in the slightest, but he'll end up having fun too.

Summary
It’s only once his eyes come back into focus that he realizes he’d been staring across the room.
Someone’s staring back, too. He’s swaying along to the music, standing within the crowd but on his own. He winks and Veritas breaks away, looking down and tracing the rim of his glass.
“Care to dance?”
A series of surprises, coincidences, and luck bring Veritas into contact with a mysterious stranger. He doesn't believe in magic, but it finds him anyway, and he falls a little in love with life along the way.

Summary
“Ratio,” he says, dropping his voice to just the pitch he knows makes Ratio crack, “this could’ve been an email.”
"Yes, I suppose it could have.”
“So why are we here?”
Aventurine gets woken up too early. He makes the most of it.
