Purpose: External pressure forces fake dating + vulnerability
New Development: Zara announces her engagement party — couples only. Both Vivian and Milo receive invites with "+1" emphasized. Zara's manager Marcus explains: "We want to see you can handle relationship energy, not just business."
The Problem: Vivian's recent ex is engaged to her cousin. Milo's last relationship ended when he chose his career over his partner's relocation.
The Solution (Milo's): "We go together. As rivals. It'll be great content."
The Party: Old money Charleston circles Vivian has known forever. She plays perfect hostess. Milo plays charming disruptor — but when her ex Preston gets condescending, Milo defends her with surprising sharpness, not his usual goofiness.
Vulnerability Moment: Balcony escape. Vivian admits she's terrified this wedding competition is her last chance to matter. Milo admits his viral success is 90% algorithm luck and he's one failed event from bankruptcy.
Almost-Kiss #2: Interrupted by Zara's dramatic entrance. They separate, shaken.
Complication: Photos of them "together" go viral. #WeddingWars becomes a trending storyline. Now they're trapped in the narrative — rivals with "will they/won't they" tension that boosts both their brands.
Subplot Advance: Eleanor Sterling sees the photos and misinterprets. She invites Milo to "family dinner" to investigate. Vivian is horrified. Milo is delighted.
