Summary
When the word tore itself apart, Sakusa Kiyoomi chose the quiet places left undisturbed.
He learned to survive, alone. Learned to leave zero traces, hide, and fight. But when the forest brought new souls, he was forced to encounter them. The twin foxes change the life he has lived, what he thought he wanted.
For the first time, Sakusa wonders if surviving is enough, or is there meant to be more to life than just being alive.

Summary
Surviving a Death Song was hard as it is. A too blunt jerk? okay your pushing it too far.
Atsumu didn’t mean to even meet the dragon, the poor thing is probably having second thoughts.
And currently merely surviving is too much.Instead, he gets Sakusa Kiyoomi: a fucking asshole who shows up at the worst possible time, thinks Atsumu is a nuisance and won’t stop butting in.
Or: Atsumu’s trying to win over a dragon and ignore the fact that his 'enemy' is annoyingly attractive.

Summary
He likes Miya Atsumu in everything he is, from the dorky emails to the way he looks, from the childish giggles to the soft, muffled laughs when Kiyoomi attempts to joke back. Yeah, no, that was terrible…
Kiyoomi smiles at his computer screen. And then he tries to gulp it down, pressing his lips against each other so hard they’re white, his nails digging into his thighs, his eyes almost bulging out because oh, fuck of all fucks.
He probably likes Miya Atsumu way too much, doesn’t he?
or: kiyoomi hates the fact that his new cybersecurity job involves reading other people’s emails. that is, of course, until miya atsumu shows up.

Summary
Atsumu needs to move out—like soon. Like in a month soon.
Sakusa Kiyoomi has an extra bedroom that—the person he thought was his friend—Suna has offered to Atsumu, without asking.
Nothing could possibly go wrong, right? A borderline agoraphobic streamer living with a larger than life man with perpetual younger twin syndrome, it’s obviously a match made in heaven.
Turns out it’s actually not so bad—but it’s definitely a bit awkward when Sakusa realizes that he’s falling in love for the first time with a loud bottle blonde who somehow, despite everything, respects his boundaries and never pushes him. Things get a little more messy when Atsumu walks in on a stream and Sakusa’s chat wants to know who the cute boy that’s suddenly living with him is.
Or; Sakusa Kiyoomi learning through a perfect stranger to let go, Miya Atsumu learning to enjoy the simple, quiet things and their journey to meeting somewhere in between.

Summary
Kiri had accepted her place as the 'freak', as the strange looking half-human na'vi that her peers found weird and unattractive, and had expected that things would stay that way forever. So when Rotxo, a relatively well-liked and popular boy that the Olo'eyktan himself took under his wing suddenly asks for permission to court her, she's thrust into a world of romance, drama, and whirlwind emotions she thought she'd never feel.
-----
In which Rotxo attempts to court Kiri, and Kiri rarely understands what's happening, but somehow it still works.
