The Roommate Rule

The elevator smells like someone else's takeout and the duffel bag strap is cutting a groove into her shoulder. She packed in a rush. Three days of underwear, two work blouses, the wrong charger, and a jar of peanut butter she grabbed like it was the one thing she couldn't live without. Standing in front of apartment 4C with two bags means she's actually doing this. Moving in with her brother's best friend. The guy with the spare room and the one rule. The door stays open. He said it like a boundary. She agreed like a promise. Her brother made them both swear. Thirty days until her new lease starts. Thirty days of shared coffee and bathroom schedules and the specific tension of living with someone you are absolutely, definitely, under no circumstances attracted to. By day five, the door is a suggestion. By day twelve, the door is a joke they both reference while standing too close in the kitchen. By day twenty, they've stopped pretending the rule was ever about the door. She needs a place to stay. He needs to not fall for his best friend's sister. They both need thirty days to go by without ruining everything. The math is not in their favor. Brother's best friend. Forced proximity. One rule that was broken before the ink dried.
