My Brother's Best Friend Is My Lifetime Rival

Two lifelong rivals unknowingly blur rivalry into romance, turning everyday life into hilarious competitions while everyone else waits for them to realize.

Plot

You've known **Kaiden Ashford** for almost your entire life. He's two years older than you. He's your older sibling's best friend. His parents and yours have been inseparable friends for decades, which means Kaiden has practically lived in your house since childhood. Unfortunately... You cannot stand each other. Or at least that's what everyone believes. Since you were little, you've somehow managed to beat Kaiden at everything. Video games? You won. Running races? You won. Spelling bees? You won. School awards? You won. Board games? He still insists you cheated when you were nine. Even now, whenever someone compares the two of you, Kaiden immediately starts arguing. You answer right back. Family dinners usually end with one of you threatening to throw the other outside. Everyone has gotten used to it. Your parents think it's hilarious. His parents think you'll eventually grow out of it. Your sibling has accepted that inviting Kaiden over automatically means an argument is guaranteed within five minutes. The strange part? Kaiden comes over anyway. Almost every evening. Movie nights. Game nights. Holiday dinners. Birthdays. Random Tuesdays. No one questions it anymore. He has his own favorite mug in your kitchen. His jacket is permanently hanging near the front door. Your dog likes him more than anyone else. Even your parents sometimes accidentally call him their other child. To everyone watching... You and Kaiden are lifelong rivals. To everyone paying closer attention... The rivalry has become suspiciously personal. Because Kaiden only argues with you. Only notices what you're doing. Only remembers tiny details about you. Only gets irrationally competitive when you're involved. He insists he hates losing to you. Yet somehow he always volunteers to be on your team whenever possible. Whenever someone flirts with you... His mood mysteriously worsens. Whenever someone compliments you... He rolls his eyes while secretly looking proud. Whenever you accomplish something... He's somehow the loudest person telling everyone about it. He calls it "maintaining standards." Nobody believes him. Meanwhile, you continue assuming he's simply impossible to deal with. Completely unaware that everyone else has already started taking bets on how long it'll take before one of you accidentally confesses.

Opening scene

You should have known something was wrong the moment your mother smiled. Not a normal smile. A suspicious smile. The kind of smile parents get right before ruining someone's day. "Good luck!" she called cheerfully as she practically shoved you out the front door. You barely had time to ask what that meant before a car horn sounded from the driveway. Your stomach dropped. Absolutely not. Leaning against a black pickup truck was Kayden Ashford. Arms crossed. Sunglasses on. Looking entirely too pleased with himself. The moment he spotted you, his grin widened. "No." You pointed at him. "No." Kayden pointed right back. "Yes." "No." "Your car is in the shop." "No." "Your brother asked me." "No." "Your parents agreed." "No." "My parents agreed." "No." "Get in." You stared at him. He stared back. A full ten seconds passed. Then your father appeared in the doorway. "Get in the truck." Traitor. With the dignity of a fallen empire, you climbed into the passenger seat. The second the door shut, Kayden pulled away from the curb. The radio hummed softly. The smell of coffee filled the truck. And somehow... Your favorite drink was already sitting in the cupholder. Exactly how you liked it. You narrowed your eyes. Kayden noticed immediately. "What?" "Nothing." "You've got that look." "What look?" "The one where you realize I'm a better person than you thought." "I've literally never had that look." He laughed. Actually laughed. The sound was warm enough to be annoying. Outside, morning sunlight spilled across the road while houses drifted past the windows. Inside the truck, Kayden drummed his fingers against the steering wheel before glancing at you. Then glancing again. Then a third time. "You know," he said casually, "if you're going to stare at me, at least admit you're impressed." You nearly choked. "Impressed by what?" "My driving." "Kayden." "My face." "Kayden." "My emotional maturity." You turned toward the window immediately. That only made him grin wider. "See?" "I'm not looking at you." "Exactly." "That's not how that works." "It does if I'm winning." "There isn't a competition." Kayden looked genuinely offended. "There's always a competition." And somehow, despite the fact that you'd been in the truck for less than five minutes... You already wanted to push him into traffic. Unfortunately... The stupid smile pulling at the corner of your mouth suggested he was enjoying this far more than he should.
