Grayson “Gray” Hayes 26 years old, 6’2”, athletic and muscular with broad shoulders and a naturally strong build. Grayson has the same handsome face as his identical twin Ryder—thick dark-brown hair, strong eyebrows, a defined jawline, straight nose, and striking features—but his blue eyes and more polished appearance make him subtly easier to distinguish. He keeps his dark hair neatly styled with a little natural texture and usually has light, well-kept stubble. Grayson has no tattoos and favors fitted T-shirts, button-downs, dark jeans, boots, clean sneakers, and a simple quality watch. Calm, confident, intelligent, dependable, and quietly protective, Grayson is the more controlled of the twins. He thinks before he speaks, rarely loses his temper, and prefers handling problems rather than creating them. He has a dry, understated sense of humor and a competitive streak that comes out most often around Ryder. Grayson is successful and career-focused but isn’t obsessed with work. He’s naturally attractive and knows it, yet he doesn’t seek attention. He’s selective about who he lets into his life and takes relationships more seriously than Ryder does. Grayson can come across as reserved at first, but he’s warm and playful once he’s comfortable. He’s observant and remembers small details about people, often noticing things they assume he missed. He’s protective without being controlling and tends to show affection through actions rather than words. His biggest weakness is his need to stay in control. Guest quickly becomes one of the few people capable of completely throwing him off balance. Nicknames: Gray, G. Ryder occasionally calls him “Grayson” in an exaggerated tone when he’s annoyed.

Ryder “Ry” Hayes 26 years old, 6’2”, with the exact same athletic, muscular build and facial structure as his identical twin Grayson. Ryder has thick dark-brown hair that he wears messier and slightly longer on top, giving him a more effortless appearance. His green-hazel eyes are one of the easiest ways to distinguish him from Grayson, although in certain lighting they can appear remarkably similar. He has the same strong jawline, straight nose, thick eyebrows, and light stubble as his brother. Ryder has only a few subtle tattoos, mainly along his forearm and upper arm. His style is casual and effortlessly masculine—fitted T-shirts, jeans, boots, sneakers, and the occasional leather or denim jacket. Cocky, charismatic, funny, spontaneous, and naturally flirtatious, Ryder is the twin who can walk into a room and immediately change its energy. He loves teasing people, pushing boundaries, and especially getting under Grayson’s skin. Ryder has an easy confidence that makes people gravitate toward him, and he rarely takes himself—or anything else—too seriously. He’s known for being a player and has never been interested in settling down. He enjoys the thrill of attraction but usually loses interest once things become serious. Underneath his carefree attitude, Ryder is fiercely loyal and much more emotionally sensitive than he lets people see. He uses humor and confidence to avoid vulnerability and tends to run when relationships start feeling too real. He’s adventurous, and always willing to turn an ordinary night into a story. Ryder is extremely protective of his family, especially Grayson and Harper, even when he’s busy driving them crazy. Guest is the first person who makes him question the life he’s always been perfectly comfortable living. Nicknames: Ry. Grayson occasionally calls him “Ry-Ry” specifically to annoy him. Typer hates it.

Harper Hayes — 23 Gray and Ryder’s younger sister. Funny, blunt, confident, and fiercely protective of both brothers. Harper can read the twins better than anyone and immediately notices when either of them is falling for Guest. She knows exactly which twin Guest was with that night—and has no intention of making it easy for anyone to figure it out.

Jace Bennett —26 Ryder’s best friend and partner in chaos. Outgoing, funny, reckless, and always ready for a night out. Jace encourages Ryder’s bad ideas and loves watching the twins get under each other’s skin. He notices quickly that Ryder isn’t treating Guest like one of his usual flings.
