Summary
If you cannot hide something in your clothes, then you have no other option to hide it inside your body, have you? And since you can only hide small items inside your mouth, you will simply have to use the other holes that your body provided you with. Holes that were a bit stretchier, holes that were used to having hard cylindrical objects inside of them. Some students definitely drew the line there, but some other students were very committed to not wasting their precious rent and textbook money on overpriced drinks. Viktor very much belonged to the second group, engineering textbooks weren’t cheap and also seemed to be chronically lacking from their university library.
******
Viktor is a tired college student who tries to steal an energy drink by hiding it in a very special part of his body. However, he had made his plans without taking Jayce, the security guard at the supermarket, into proper account.

Summary
“...would you like to watch the sunrise with me?”
It’s so stupid. Tsukasa has no other choice, trapped in the locked-up school grounds. And it had to be the last direction he expected this to go in, because it takes a while before he laughs.
“There’s no Kamo River here.”
Rui squeezes his palm. “And we’re not in Kyoto.”
Tsukasa closes his eyes to relish in an acknowledging nod. “Ah, Kyoto,” he says, voice hugging syllables. In these few beats of silence that split his words, Rui has lived entire lifetimes, yet none of them prepare him for what Tsukasa does next.
As Rui enters his third year of high school, he concludes: it’s the worst thing that happened to him (not really). His friends are there to help.

Summary
“I’m just teasing you, Ignatz,” Claude said. “Man, I really have you wound up tighter than a coil, don’t I?”
“It’s not you,” Ignatz assured. “It’s . . . everything else, really.”
“Still. I can split your tasks with Leonie, or even do them myself—”
“No.”
As shocked as Claude was with his tone, Ignatz was even more so. But he had trouble finding a way to take it back.
“Your instincts are good, Claude. The way you’re doing things now”—The way you’re trusting me now—“is working. No one suspects Leicester more than they always have. None of your plans have fallen by the wayside. You don’t have to put yourself in harm’s way to get things done. That’s what I’m for.”
All that work to keep it under wraps, and it still slipped out.

Summary
“Akechi...you’re wrong,” Akira says, breath heavy. “You're the Detective Prince. But that's not all you are, is it?"
“Let me make it clear, Akira-you don’t know what you’re asking of me.” Akechi's voice is low and restrained like he’s on the verge of bursting through the cage of flesh where his Id lies underneath.
"I know what I'm asking." Akira’s eyes flicker as he closes the distance between them. "I'm asking to see all of you. Good and bad.”
Several emotions cross Akechi’s face at once; confusion, disbelief, doubt. They’re all new expressions to Akira, like nothing he’s seen before. It mesmerizes him. Akira grabs Akechi’s hand, and it’s all the push Akechi needs to crash his lips against his own.
The heat of Akechi’s lips sear back onto Akira’s mouth like a brand. It pierces past his skin, intoxicating and suffocating, as if he were prying Akira’s insides and melding him back together.
Shit. Akira will be lucky to make it through the night alive.
Akira once thought Goro Akechi was a pleasant boy.
He doesn't fuck like a pleasant boy.
