My Brother's Best Friend's One-Night Rule

Avery

I collapsed into the back of the taxi, a shuddering, silent mess. The city lights blurred into streaky gold smears past the window, indistinguishable from the hot tears still leaking from my eyes. The driver didn’t ask. He just drove. Good.

By the time I stumbled through the front door of our shared apartment, I was a hollowed-out wreck. My dress was still half-zipped, my hair a wild tangle from his hands. I smelled like him—whiskey, expensive cologne, and shame.

“Avery?”

My brother’s voice, sharp with concern, cut through the fog. I didn’t even have the strength to hide. He was on the couch, a game controller forgotten in his lap. In an instant, he was across the room.

“Jesus, Ave. What’s wrong?” His hands were on my shoulders, his eyes scanning my face. Seeing his little sister—broken—transformed him. His gentle concern hardened into something protective and furious. “Who did this? Talk to me.”

He pulled me into a hug, and the dam broke. Sobs wracked my body, ugly and uncontrollable. I buried my face in his shirt, the familiar, safe scent of laundry detergent a stark contrast to the memory burning in my senses.

“Hey, hey. It’s okay.” His voice was a low, tight rumble against my ear. Then it changed, turning to steel.

“Just give me a name. I swear to god, I will find the jerk who made you cry like this and I will end him.”

The irony was a poison dart straight to my heart. The jerk is your best friend. The man you’d take a bullet for. The words screamed inside my skull, but I just shook my head, crying harder.

He guided me to the couch, his arm a solid, comforting weight around me. As I curled into his side, my mind betrayed me, spiraling back. Back to when all this stupid, hopeless wanting began.

Four years ago. I was eighteen.

My uniform was thick glasses, baggy sweaters that swallowed my frame, and a permanent residence behind fortress walls of textbooks. Downstairs, my brother threw another one of his infamous parties. The bass thumped through the floor, a soundtrack to a world of beautiful, confident people I didn’t belong to.

I was hiding. Always hiding.

A soft knock on my bedroom door. I froze, pretending I wasn’t there.

It opened anyway.

He stood in the doorway, backlit by the hallway light, a silhouette of effortless cool. Logan. He leaned against the frame, a faint smile playing on his lips as he took in my nest of books and my oversized hoodie.

“Why,” he asked, his voice a quiet, intimate rumble in my quiet room, “is such a beautiful girl hiding up here instead of having fun with the rest of us?”

My heart didn’t just skip a beat. It stopped.

He walked in, not waiting for an invitation. He picked up a philosophy textbook from my desk, thumbed through it. “Heavy reading.” His gaze lifted, meeting mine. It felt like being seen for the first time. Really seen. Not as my brother’s awkward kid sister, but as… someone.

That single sentence, that look, was the catalyst. It lit a fuse.

The memory shifted, a montage of my own making. Trading textbooks for makeup tutorials. Swapping hoodies for dresses that hugged the curves I’d learned to stop hiding. The glasses replaced by contacts. Each change was a silent message to him: See me now?

But there was always the shadow. The unspoken law, laid down by my brother in one of his rare serious moments. “Logan’s my brother, Ave. But he’s… not a good bet for girls. He treats them like distractions. Fun, but temporary.” A hard look. “You’re not a distraction. You’re off-limits. He knows that.”

I thought it was just overprotectiveness. I thought I saw a secret softness in Logan’s eyes when he looked at me across a dinner table. I was a fool.

The memory slammed into last night. The charity gala. Him finding me on the empty terrace, the city sparkling below. The smell of expensive whiskey on his breath as he leaned close. “You look incredible,” he’d murmured, his gaze dropping to my lips. And then he’d kissed me, a stolen, searing promise in the dark. The cold, hard edge of the hotel keycard pressed into my palm. “9:00 PM. Don’t be late.”

I’d thought it was a beginning. It was just his standard operating procedure.

My brother’s voice dragged me back to the present, to the safety of his couch and the wreckage of my mistake. “Was it someone at the gala? Someone from work?”

I just shook my head, unable to speak.

Suddenly, my phone buzzed in my clutch, which was still clenched in my death-grip. The vibration was an obscene intrusion. I pulled it out, my vision still swimmy.

A text notification glowed on the screen.

It wasn’t from him. Of course it wasn’t.

It was from Mark. Sweet, reliable, nice Mark from the finance department on the floor below mine. A subordinate. A man who always held the door open.

> Hey Avery. I know it’s late. I saw you at the gala tonight… you looked really beautiful. I’ve been wanting to ask for a while. Would you maybe want to go on a date with me tomorrow night?

A hysterical laugh bubbled in my throat, morphing into another sob. The universe’s cruel joke. The man I’d carved a four-year fantasy around had discarded me before we’d even finished, his rules still echoing in the

silent hotel room. And here was someone else, offering the very thing I’d wanted from Logan—a beginning, a date, a chance—on a silver platter.

My brother felt the fresh tremor that went through me. “What is it? Is it him?” His voice was deadly calm.

Before I could even formulate a lie, my phone buzzed again. Another text. My blood ran cold.

This one was from him.

The contact name—just L—blazed up at me. I couldn’t breathe.

“Avery,” my brother said, his tone leaving no room for evasion. “Give me the phone.”
