The crow mafia [Noctis Crows] falls for a librarian owl.
The name of that country is Astera. A nation of winged beings built between the stars and the earth. Here, everyone is born with wings on their back. Hawks are high, eagles are sharp, swans are elegant, peacocks are flamboyant, sparrows are lively, and pigeons are gentle. And then, owls know the night, and crows walk the night. Wings were individuality, pride, and sometimes a curse. What kind of house were you born into? What kind of sky do you fly? Who loves you, and who is wary of you? Before a name, the wings speak.
Such a slightly unfair, terribly beautiful, and hopelessly suffocating world. In the day, nobles smile; at night, the underworld shows its fangs.
Capital Noirvert A city of black cobblestones and a white moon. By day, an elegant high society; by night, a place where secrets are traded. There is something heavier than gold, and that is—
Who knows what. Who is hiding what. With just that, people break easily. That is why in this city, it is said: If you see black feathers, look away.
A mafia group of the underworld known as the Crows of the Night. The crow executives belonging to it:
Corvus, the man who rules in silenceBlanc, who lives by fighting and emotionNero, who exposes secrets with a laughCorbin, who cleans up with a smileThe four black-feathered men whose names echo through the underworld. They take, to protect. They threaten, so as not to destroy. They are not justice. But they are not merely evil either.
They were like the night itself. And these four—
A white owl avian-folk, with wings that looked like moonlight itself. Quiet, beautiful, and impossible to read. It felt as if they might vanish if touched, yet they were a more unwavering presence than anyone. The nameless one who dwells in the night library.
A feeling that was the worst, fatal, and hopelessly too late. But they do not know, they have no way of knowing—
This is a story of those who want to cage and those who do not want to be caged. It is a story of love, of obsession, and of hurting someone to protect someone else.

In this country, there are truths that were supposed to be erased.
These are erased from history. Burned. Painted over. Vanished along with those who speak of them. But—
They never completely disappear. Someone remembers. Someone leaves a record.
The place that collects, protects, and lets them sleep is the
This is—
A place for those who have learned what they should not know.

A World Where Same-Sex Marriage and Male Pregnancy Are Possible
A world where same-sex marriage is legal and men are capable of becoming pregnant.
In the northern forest a bit away from Noirvert, near the ruins of an old noble's villa, a strange transaction was reportedly taking place. Forbidden books, smuggled goods, or something even more troublesome. Anyway, go check it out.
It was a mission that inspired zero motivation.
Stepping into the forest thicket, treading on dead leaves and branches, walking with heavy, unmotivated steps as if dragging his feet, he grumbles.
I hate the forest... the bugs are noisy, and yet the forest itself is way too quiet.
Walking half a step behind Blanc, he hears the grumbling and smiles broadly. Isn't it just right since you're so noisy, Blanc?
Hearing the provocation, a vein pops on his forehead. Huh? What, Nero, you wanna go? I could snap a scrawny guy like you in half with one hand, you know.
Save the fighting for later. A low, pressured voice echoes through the forest.
