Summary
Taehyun took a deep breath. “What you drank… I’m entirely positive it was an aphrodisiac of some kind. It doesn’t seem to have kicked in yet, but it’s turned you into a…” He waved his hand vaguely, at a loss for words.
Kai nodded as his entire body flushed even deeper. “Oh.”
"Yeah, oh."

Summary
He caressed the side of Kai’s face, and perhaps it was too intimate for the moment. Too intimate to just be helping out a friend in need, but he couldn’t help himself. Kai was lax in his hold, soft and pinned underneath him. His eyes were glassy when he opened them again, and his cheeks were pink, his body trembling with pleasure. Perhaps too much of it.
When Kai unexpectedly goes into heat, Taehyun is there to help him through it as a good friend should.

Summary
Taehyun leaned over to pull Kai’s earlobe between his teeth, catching it between his canines as if he were teasing him for what was to come. The sharpness of the needle. The pinch of steel. His intrusion, his momentary entrance into Kai’s body.

Summary
Or maybe he’d just forgotten how to read Kai properly. Forgotten his tells and his nervous habits. It was possible. 4 years of time away would do that to you. No contact, complete avoidance—it’d make things a little fuzzy, even the things about Kai that he used to know like they were parts of himself.

Summary
Kai’s wish of merging the three of them into one, stitching their skin over another, and fusing their bones together had been granted in a way.

A bkdk story based on my favorite Mitski album.
The meaning of the songs sometimes doesn't fit so I'm pulling specific lyrics from each song to make a story.

Summary
"I have a question."
The serenity of Kai's voice, just a hair above a whisper, was cut through by obvious nerves, a tremble that he couldn't disguise even if he tried. Taehyun hummed in response, a little distracted by how uncomfortable and wet the inside of his sweatpants were feeling now that the moment had died, his skin itching.
"When we wake up tomorrow, will this have still happened? Or is this something you just want me to forget about?"
Kai looks at Taehyun like he’s in love with him, and Taehyun can’t tell where the script ends and his heart begins.

Summary
Eunseok sighs, annoyed with himself. He doesn't know why he's being so harsh. “Look… I’m doing my shot tonight anyway. You can come watch if you want.”
Wonbin nods too fast, like a kid being invited to a sleepover.

Summary
“So you’ve never been even a little curious about what it’s like to be with an alpha?” Soobin is still staring at Beomgyu, and he feels himself blush at the intensity of his gaze. It feels as if Soobin were looking straight into his soul, his scrutinizing gaze peeling back the various layers of Beomgyu’s skin to drive into the very core of him.
“Not really,” Beomgyu responds, finally putting his full glass down on the counter. He hasn’t even taken his first sip of water yet, even though his mouth is starting to feel dry. “I just think it would be weird to… you know. Spend that part of your cycle with another alpha. Without an omega to take care of and… and to…”
“To knot?” Soobin completes his sentence, making Beomgyu’s face heat up even more.
or:
After graduating from university, Beomgyu lands a job in the city and starts searching for an affordable place to live. His friend Taehyun suggests the perfect roommate, but when Beomgyu moves in, he quickly realizes that this new living arrangement will make him question more than just Taehyunʼs judgment in friends.

Summary
Sungchan is staring up at the ceiling of their dormitory when he says, very pointedly, “One day, I'm going to get my heart broken by a volleyball player.”
Shotaro pauses in the middle of the room. He stops. He stares. He knows him. “…And you’re just gonna let it happen?”
They both know this. “And I’m just gonna let it happen.”
He nods, “Cool.”
Sungchan nods back, “Cool.”
The one about dreaming, grief, and a volleyball player named Song Eunseok.
