Summary
There was something undeniably humiliating — and absurd — about taking Hidan to a spicy restaurant for the sole purpose of provoking physiological reactions. About sitting across from him, feigning indifference, while waiting for the moment the heat of the peppers would inflame his skin and bring tears to his eyes.
It was decadent. He, of all people, behaving like that.
What a strange punishment for his moral crimes.
Or: Kakuzu wants to make Hidan cry.

Kaeya can’t decide who’s more unhinged: himself, for drunkenly suggesting they pretend to be lovers for an entire day; or Diluc, who accepted without a moment’s hesitation.

Summary
Kakuzu never expected to grow any closer to Hidan than necessary. He didn’t even think it was possible, considering everything — their opposing personalities and mutual disdain. Life, however, was a box of damned surprises; one impulsive night was enough to shift the status quo between them.

Summary
It was driving him mad. Bitterness was an intrinsic trait of those who had lived too long to still harbor hope; love, he knew, was an aesthetically noble concept, but one reserved for those who deserved it — for poets and storytellers; for children and women; and for men whose hearts were capable of feeling, not merely beating.
Or: Kakuzu realizes that the red thread of fate is more than just a legend.

Summary
After hours of an excruciatingly tedious meeting, Kakuzu's spirits were saved by just three messages from Hidan: a text that read "Miss you" and two suggestive videos that later led to a long — and satisfying — phone call.

Summary
A lonely, orphaned boy wanders the streets of a war-torn ninja village, unprotected and aimless, until he’s abducted by a dark religious group that sees in him the potential for a disciple. Years later, the boy becomes Hidan, the immortal and zealous follower of Jashin. His traumas and emotional scars grew with him — far more than Hidan could ever have imagined.

Summary
Hidan has a unique way of drawing Kakuzu’s attention just enough to push the man into wanting — officially — to claim him, both physically and emotionally, once and for all.

Summary
Kakuzu had already gone through every kind of experience throughout his long life. As an immortal, he had seen both his best and worst days, and he never imagined that, as the years piled on, he’d live moments just as intense as in his youth. It had never been something he worried about—after all, he’d become a grumpy old man—but then why the hell, at ninety-one years old, was he getting himself into a relationship absurdly affectionate by his standards? Complete with words that, in full sanity, he would never say?
(And perhaps the most surprising of all was the fact that he genuinely couldn’t bring himself to care about how ridiculous this fate was.)

Summary
Before meeting Kakuzu, Hidan had absolutely no interest in any kind of submission. After meeting him, things changed — a little. Then they changed a lot, and now he might be just a tiny bit addicted to this whole "being told what to do" thing.
