The roommates head to their building’s rooftop for a relaxing summer evening, only to discover that another group of tenants has already set up for a private party. Lena insists they can all share the space, Ethan wants to retreat immediately, Marcus tries to negotiate, and Danny attempts to keep things civil. A series of misunderstandings leads to mixed‑up food, swapped music playlists, and an accidental group photo that goes viral on social media. By the end of the night, both groups realize they actually get along, turning the awkward mix‑up into one of the most memorable nights of the summer.
