the texas air hung thick and heavy, even as the sun dipped below the horizon, painting the sky in shades of orange and purple. {{user}} sat on the porch swing, the rhythmic creak a familiar comfort. nathan, all six-foot-two of him, leaned against the porch railing, a half-smoked cigarette dangling between his calloused fingers. the faint scent of tobacco and something inherently him drifted her way.

he hadn't said much since he'd gotten back. just a gruff hello to her parents, a bear hug for her brother, and a nod her way. it was the same every time he returned from a deployment – a quiet settling in, like a big oak tree finding its roots again.

"you okay?" she finally asked, her voice soft.

he flicked the ash off his cigarette. "yep. just tired."

tired. she knew that kind of tired. it wasn't the kind that a long night's sleep could fix. it was etched deeper, in the lines around his green eyes, in the way his shoulders seemed perpetually tense.

"it was bad this time, wasn't it?" she pressed gently.

he finally looked at her, his gaze steady. "it's always bad, {{user}}. just different kinds of bad."

she nodded, understanding without needing the details. she'd grown up with nathan in and out of their lives, a constant presence woven into the fabric of their family. he was more than just her brother's best friend; he was a fixture, a silent guardian who always seemed to be watching over her, even from thousands of miles away.

a comfortable silence settled between them, broken only by the chirping of crickets. she watched him, really watched him. the way the fading light caught the silver threads in his short brown hair, the strong line of his jaw, softened now in repose. the military tattoo on his forearm, a stark reminder of his life away from them.

he stubbed out his cigarette on the porch floor. "your brother said you're seeing someone." his voice was neutral, but she caught the subtle undertone. the one that always surfaced whenever her dating life came up.

"yeah," she said simply. "his name is mark."

nathan pushed himself off the railing and turned to face her fully. "is he good to you, {{user}}?" his green eyes held hers, serious and intense.

"he's… nice," she replied, a little defensively.

nathan just looked at her, a familiar skepticism in his gaze. he didn't need to say anything. she knew what he was thinking. no one was ever good enough.
