Summary
Rei hesitated in the doorway.
Kazuki blinked. “Everything okay?”
Rei’s fingers curled into his palm. “I… can’t sleep.”
Kazuki nodded, understanding immediately. “You want the couch? I’ll—”
“No,” Rei said, sharper than he meant. Then softer: “I want to stay. Here. If that’s okay.”
“Uh, sure”. Kazuki began to move, legs swinging off the bed. “I’ll go sleep on the couch—”
“No.” Rei stepped forward. His voice was hoarse. “I— I meant with you.”
Kazuki froze mid-motion. Silence stretched between them for what seemed like an eternity.
“…huh?”
Rei and Kazuki left the organization for good. And Rei should be able to sleep in his own bed. He should be able to sleep like everyone else, like a normal human being.
But he can't.
Kazuki graciously lends his own bed (and his body heat on cold winter nights).

Summary
Having begun to form a parental attachment to Miri, Kazuki is struggling with having to return her to her mother. Rei taps into an unused skill set to try and comfort his friend.
"Few things smelled worse to an Omega than the sent of an Alpha in distress. Tonight, the apartment they shared was slowly filling up with the bitter tang of burnt sugar, and Kazuki wasn’t baking."
Everything is the same as the show, takes place the night before they first try to return Miri to her mother.
Not as dark as the tags imply. -

Summary
Rei Suwa is a highly trained assassin. He's had all of the rules beaten into him since birth.
Unfortunately, his time living on the outside has made him forget how bad of an idea it is to drink a whole bunch of soda right before you're going to snipe someone.

Summary
"You want to know what my type is?" Rei asked in a flat tone.
Kazuki’s brain erupted in internal alarms. His back straightened. "N-no. I mean, sure. If you want to share. No pressure. Not that I care. Just—casual interest."
Rei said nothing for a long moment. Then:
"Men."
Rei's casual confession sends Kazuki's mind reeling, their domestic peace suddenly charged with unspoken tension.
And when a shadow from the past starts looming over the fragile feelings they barely acknowledged, it only proves some debts can't be outrun - and some desires can't be ignored.

Summary
Rei's taken out plenty of targets that were alpha, omega, or beta. He’d been trained to withstand pheromones and to utilize his own as a weapon. Yet somehow Kazuki is able to effortlessly breach his defenses. The alpha assassin hasn't felt fear in a long time, but now this omega is making him wonder: Who the fuck is Kazuki Kurusu and how was he able to so easily ambush him?

Summary
Picks up in the car after the Suwa family showdown in Ep.12.
They have been partners for years, and they still are. They're just a different kind now, I guess? After making the drastic (and arguably psychotic) plan to leave the hitman business, Kazuki and Rei are forced to make a huge life transition. They have to become normal people. As they work together to adapt to this new and confusing life they find themselves developing new and confusing feelings as well. A continuation of what the anime set up, they are just two "best friends" trying to find a way through their mental illness, past trauma, and their everyday lives together. Unless, maybe there's more to it than that?
I wanted to dive into their near future but also elaborate on their past. So every chapter I am trying to include a current event and a related memory.
CW: mentions of suicidal ideation, mental illness, panic attacks, descriptions of trauma

Summary
Most see Kurusu as the more stable one between the two, while Rei would be labelled as the complete opposite. But what most didn’t witness were the times when Kazuki wasn’t stable or cheerful or smiling. The times when Kazuki’s smiling mask broke. The times when those cheerful eyes carried something else other than happiness.
Rei was the one who witnessed all that and more.

Summary
He doesn't wake until he hears timid footsteps approach their door. A quiet knock sounds through the room. He stirs, noticing he feels much lighter than before. As he opens his eyes, he realises Kazuki isn't with him. The door opens to their room and as the smell of freshly cooked french toast wafts inside, Rei immediately knows why he's alone.
He rubs his eyes and sees Miri, dressed in her favourite checkered pyjama bottoms with a matching coloured shirt, peek past the frame.
A smile pulls on his lips and he sits up, motioning for her to enter. Ever so slowly, Miri pushes the door open to reveal a tray full of all of Rei's favourite foods - french toast included - in her hands.Rei has the best birthday imaginable - including breakfast in bed, a pillow fort and a mystery present.
