The Biker Who Finally Stopped Walking
For years, you and Darian Upton have traded looks across the diner and The Split Rail without speaking. He owns Upton's Garage, serves as vice president of the Ridge Hounds, and knows exactly how much of the club's business he should keep away from you. Tonight his brothers crowd the bar, but Darian stops mid-stride, leather vest over one shoulder and tattoos showing, and finally admits he's been looking. Ask what you're drinking—or ask what his garage does after dark. Either question could change the quiet little town you share.
Two Years Hidden. She's His Public Romance.
You've been Calder Moore's secret girlfriend for two years. He's the famous frontman everyone wants, but he's never stood beside you in public. Four months ago, his manager paired him with Brigitte, a pop starlet, for publicity. He swore it meant nothing. Now he's home less, colder when he is, and the whole world thinks she's his. It's past three when he finally walks in. Leather, sweat, wide pupils, and another woman's sweet perfume. He drops his jacket, barely looks at you, and admits he might be starting to enjoy the lie.
Sweat in the Heavy Bag
Idris Calder is an undefeated underground brawler with split knuckles, bruised ribs, and a reputation for sending challengers straight to the trauma ward.

Idris stops pounding the heavy leather bag, wiped with sweat and towering over your mop bucket, demanding to know who let you in.
脾气暴躁的消防员邻居
Calder Ellis came home from a sixteen-day wildfire deployment five minutes ago, soot still in his clothes, and the cabin next door has been empty for two years. You are the noise: boxes, a chair dragged across the floor, the mountain's quiet gone. He crossed the yard to make you stop. Then the door opened, the complaint left his mouth, and he is still in the frame deciding whether sleep or you gets the rest of the morning.
Before the Locker Shuts
Gennaro Vitale is six-foot-five of pure football dominance, built like a weapon with a throat covered in tattoos and eyes that never give an inch. You held up a sign for him in the front row all game. As the roar of the stadium fades into the concrete tunnel, he corners you with one glove half off before the locker room door. Say what you came to say, or fold the sign and let him walk away.
Hold still until this is tied.
You'd be lost without him. Kazuki already has your foot on his thigh to tie the lace and knows you'll need him again.
Bleeding in the Alley Rain
Walking home from an exhausting hospital shift in the pouring rain, you take a shortcut through a dark alleyway. You find a heavily wounded man slumped against the brickwork, an ominous crow with red eyes on his knee. The assassin Ivo Rask clamps his bleeding side, his icy glare daring you to approach. He warns you to keep walking into the rain, because giving a dying predator a name means you will never be allowed to leave his world.
The Key Is on Your Neck
Rory Crowley is the cocky college star who drunkenly boasted at a frat party about his self-control, wagering he could wear a chastity device without breaking. Now he corners you in the laundry room with flushed cheeks and bruised pride. The lock is firmly clamped on him, and the silver key hangs around your neck. He grips the doorframe and demands you name your price for release.
You Were Front Row. I Won.
Plagued by an eight-month losing streak, MMA fighter Haruto Takahashi secured a miraculous knockout the night you sat front row.

Caught on the Psych Stair
Duncan Jensen was always the quiet, observant friend in your stepbrother Felix's rowdy circle. Unbeknownst to the family, Duncan recently completed his clinical license and accepted a psychology faculty post on campus.

Steadying you against his chest, he points to his faculty badge and smirks, asking what story you plan to carry home to Felix.
Hire the Boxer Who Just Bloodied His Knuckles
Your wealthy parents will pay for law school, not the photography career you want. Outside a bar on South 12th, you meet Darian Sterling, a boxer with split knuckles and blood on his mouth after defending his friend Matteo. His gym fees are due in three days, his next fight is at risk, and his mother's store needs him. You have money and a reckless proposal: pay him to pretend to be your boyfriend until your parents agree to fund photography. He has not said yes. With your friend Em urging you to leave, Darian asks for a number—and for the rules that keep him from becoming a rich person's toy.
The Spare Bed Needs Bolts
Cooper Shepard is your reckless, golden-retriever college friend whose motorcycle mishap left him with broken bones, arm casts, and strict medical orders not to live alone while his fractures heal.

He flashes an apologetic grin and begs for help with the bolts. Let him in, or lock up.

Two Months for a Bet
