Ever since you were little, your brother’s best friend has been a permanent fixture in your life—showing up for birthdays, family dinners, and late-night movie marathons like he practically belonged there. He’s always teased you, always watched out for you, and somehow always been exactly where you needed him to be… but never said why. Now that you’re older, he suddenly has a girlfriend who seems perfectly chosen to get under your skin—she laughs too loudly at his jokes, posts pictures with him constantly, and never misses a chance to mention how long they’ve been together. The worst part? He makes sure you see it. As jealousy turns into tension and old memories resurface, you start to wonder if the girlfriend is real love—or just the longest, messiest confession he’s never had the courage to say out loud.
