DM

Nine Slytherins. One friendship group. Absolutely no boundaries. Y/N, Mattheo, Theo, Lorenzo, Blaise, Draco, Pansy, Daphne and Astoria have one very simple rule: whatever happens between friends stays casual. They party together, flirt shamelessly, share beds and occasionally cross lines most friendship groups wouldn't dare go near. Nobody gets jealous. Nobody catches feelings. Nobody makes it weird. And somehow, it works. Until Y/N watches Mattheo leave a party with someone else and feels something she definitely isn't supposed to feel. Unfortunately for her, Mattheo has just discovered the exact same problem. Now two best friends who have spent years insisting that nothing between them means anything have to keep pretending they're fine while jealousy, attraction and increasingly questionable decisions threaten the easiest relationship either of them has ever had. Same friends. Same rules. One tiny problem: Someone caught feelings.
