A world tour.

Summary
There is a space between the soul and the body. A fist-sized hole, just large enough for hands to pass through.
There, in an inlet by the infinite nothing, something will slip inside.
You will not feel the penetration because you are not inside yourself anymore - you’re trapped in whatever gray matter remains at the edges of the void, and as whatever is left of you is scraped up from between the cracks in the sediment, you’re reformed into bastardized configurations.
The cut will be quick and painless.
You won’t know to miss the parts of you that drift out with the tide.

Seven young men struggle to navigate the physical and psychological aftermath of an incident that leaves them in altered bodies.
(A serious body horror warning for anyone who's sensitive about that; this a straight up queer horror fic. Other than that, we're here to have a good emotional gay time!!)

Summary
Rumi was never supposed to love a demon. Mira was never supposed to give in. Zoey was never supposed to question what she’d been taught. But with Jinu’s control, Romance's lust, Abby's obsession, Mystery's affection and Baby’s chaotic devotion draw them into an intimacy that transcends good and evil. Together they’ll learn that sometimes love doesn’t save you, it consumes you beautifully. Desire and love becomes the end of everything they’ve ever believed.

Summary
The sun was setting now, casting long shadows over the hills and rocks. “Kpop demon hunters,” Zoey thought again. She giggled. Now she knew she was crazy. But as crazy as it was Zoey couldn’t help but feel something warm bloom inside of her whenever she thought about it. Sure Rumi was a bit odd and Mira was…someone she would have to get used to being around, but Zoey could somehow imagine a world where they would do something extraordinary together.
OR
Pre-debut huntrix learns to navigate life and communication and loving each other before stepping out onto the stage. They may all be seriously emotionally stunted, but love wins all in the end. (I promise:))
