Summary
If Kai wanted to be walked around on a leash, Taehyun could do that. There wasn't much that Taehyun couldn't learn. There wasn't much that he didn't want to learn. In fact, he could probably do it better than anyone else Kai was seeing right now.
In the midst of their comeback preparations, Kang Taehyun adopts a puppy.

Summary
“Did I ever do something? Like, we’re cool, right? Are you… mad? If I did, I’m really sorry.”
Taehyun smiled. Just the corner of his lips, a small, barely there thing. “No, we’re cool.”
“Okay. That’s good.” Kai sat back, taking the answer but not quite believing it.
After a series of awkward interactions, Kai was convinced Taehyun didn't like him. When he woke one day to find that he could suddenly read every one of his thoughts, Kai quickly found that wasn't the case at all. In fact, it was quite the opposite.

Summary
The moon was at its fullest, soft light and night glow coming in to cast shadows against Kai’s face. It caressed her like the knuckle of gentle fingers across her cheek, tender and cradling. Yeonjun wanted to swat it away. She wanted to keep Kai for herself and gather her up in her arms, hidden away from the sun and the moon and all the darkness that would be left when both were cast away.
Biting into Kai felt like coming home.

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.

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
Taehyun placed a tennis shoe on his chest and leaned close.
“Spit at Kai again and I’ll see how far I can fit my foot up your ass. Might even be able to rearrange those ugly teeth of yours for you,” he said, very quietly. Kai had never heard him use such language.Without saying another word, he turned to Kai. “Let’s go home, yeah?”
Kai nodded. For some reason, the front of his pants were really tight right now. The last time he’d gotten an unfortunate boner was middle school, why was it happening now? He pulled his bag off his back and held it in front of him to try to keep Taehyun from noticing.
“You’re okay, right?” Taehyun asked. “He didn’t hit you?”
“N-no, no, I’m good. I promise I’m fine, I’m just– you know. In shock, that’s all.”He’d never gotten a boner in shock before, but there was a first time for everything.

Summary
Anton’s mouth opens, then closes. He looks Sohee up and down, gaze sticking on his throat, his jaw, then back to his eyes.
There’s a beat of silence, heavy and pulsing, and then Anton blurts, so fast he almost trips on the consonants: “I can’t knot anymore.”
Sohee, who’d been braced for an awkward confession—maybe a secret crush, maybe some embarrassing group dynamic shit—just stares at him. “What?”

Summary
Of course Taehyun follows Kai’s onlyfans. He even makes a big show of it, downloading the app right there on the couch while they share a piece of cake Kai stole from work. He thinks it’s better this way, keeping his relationship with Kai’s onlyfans as a sort of friendly running joke. Maybe if they normalize it, if it’s a part of their every day banter, his imagination won’t run as wild.
He turns on Kai’s post notifications too, but he doesn’t show that bit off, waiting until he’s in the safety of his bedroom to do so. He forces himself to leave the app immediately after, locking his phone and hooking it onto the charger with Kai’s plush thighs still fresh on his mind.
