Summary
“Grace, question?”
I perk up at the sound of Rocky's voice. It's not uncommon after almost two years into our trip to Erid to ask random questions about me, or humans, or really earth in general. Especially after an hour or two on his computer.
“Yes Rocky?”
“Humans persistence predators, question? Humans hunters, question?”
“Ah.”

Summary
“Does bonding with you mean you’re mine?” he asked with nearly a childlike wonder.
Gasps erupted behind them.
Familiars did not speak aloud.
Shen Jiu ignored everyone else completely.
“It means you're mine,” he corrected coolly.
The creature’s eyes narrowed pleasantly.
“Ah,” it said softly. “That works too.”
Shen Jiu wants a powerful familiar. An intelligent familiar. A familiar worthy of the Academy's top student.
What he gets is Shen Yuan.
Or:
Shen Jiu accidentally summons an eldritch horror with the personality of an affectionate cat and discovers that everyone else's survival instincts are dramatically overdeveloped.

Summary
Tim got used to it. The organized chaos. The chirping and cooing and occasional feathers in his coffee. The flock of doves following him around and nesting in his drawers. The murder of crows bringing him shiny trinkets and stealing his pens. It became his normal.
For over a year and some change, the Nest felt full. Lively. Predictable, even.
Until the day he came home from patrol, coffee in one hand, data chip in the other…
…and found a raven sitting on his desk.
Just—there. Like he owned the place.
Staring.
Silent.
Still.
Like a ghost.
And Tim—Tim just blinked and said, "Okay. That's new."

Summary
【INITIATING MISSION: ‘Become a True Catboy or Fucking Explode!’ ₍^>ヮ<^₎ .ᐟ.ᐟ START】Shen Yuan transmigrates into early PIDW as a cat demon and gets picked up by the scum villain! Now his system keeps giving him cat-related missions such as ‘cats must play!’ or ‘all cats purr!’ and even ‘cats often go into heat!’. Ignore that last one, actually.
So begins Shen Yuan’s balancing act of completing these nonsensical missions, hiding his identity, and staying on the good side of the super tsundere, cat-like man known as Shen Jiu, who keeps saying stuff like ‘I’ll kill you if I find out you’re a demon’.
TDLR; this whole fic is an elaborate excuse to write catboy!SY going into heat.

Summary
Shen Yuan transmigrates into Wife #86, an unnamed catgirl demon, and decides she can't possibly pass up this golden opportunity to see her favorite protagonist in action. Her manhood was a small price to pay!
...She didn't think it would involve this much dual cultivation, though! PIDW certainly wasn't kidding about the protagonist's insatiable appetite! Hey, what happened to the other wives...?
