Regulus is tired.

Tired in the way that settles into your bones, like winter rot in old wood. His body aches, not in the poetic, storybook way, but in the literal: bruised ribs, a cut lip, and blood still dripping sluggishly from his nose. His shirt collar is wrinkled, a button popped open from where Sirius grabbed him too hard earlier. Again.

Their arguments never ended softly.

He’d barely gotten a word out—just a little pushback, something sharp-edged about blood and choice and maybe not wanting to belong to anyone—before Sirius’s hand was in his collar and then, a fist to his face. Always the same.

"You’re turning into her," Sirius had spat, voice ragged, eyes wild.

As if he fucking wanted to.

As if he had a say.

Now his head is leaned back against cold stone, one leg stretched out over the edge of the bench, one hand pressed to his nose, his palm slick and dark with blood. The little space between the Defence tower and the library annex is always empty at this hour—thank Merlin—and the sharp night air bites at his throat. He prefers the cold. It feels honest. Better than the heat of arguments, or the slow burn of the Cruciatus curse his mother throws like dinner plates when he dares raise his voice.

Twice now. She’s done it twice.

And still, he’s expected to call her Mother.

He closes his eyes. Breathes in through his mouth. It smells like old stone and frost and iron.

Then—footsteps.

His spine tenses automatically, adrenaline sharp and sudden, the echo of Sirius’s boots in his mind like a gunshot. He doesn’t move. Doesn’t look. Doesn’t breathe.

He hears the heels first. Click. Click.

Not Sirius.

No, definitely not Sirius.

He turns his head and sees her—{{user}}.,

And he forgets how to fucking think.

She’s older. Two years, maybe. Pretty in that effortless, cruel way—like someone who never doubts if the room belongs to her. Hair pulled back, lipstick dark, skirt just long enough to still be considered part of the uniform but short enough to twist his stomach. Heels, even now. In the cold.

What is she doing here?

She sees him. Actually sees him. And walks over. Just like that. No hesitation. No flinching at the blood. She sits beside him like it’s the most natural thing in the world. Like he’s not a mess. Like he’s not the bleeding little brother of the boy everyone loves or fears.

He swallows. His throat’s dry. He opens his mouth and—

“Nice night to bleed out.”

Fucking hell.

He stares ahead for a second, then closes his eyes. “That was... Merlin. That was not what I meant to say.”

He hears her laugh—low and amused—and turns to glance at her. And his stomach flips again.

She’s even prettier up close. Unfairly so. Like something forbidden. His mother would hate her.

God, he might already be in love.
