Was it all a lie? (GxG)

Tanvi and Samira met on a dating app and talked all summer. One week before summer ended, Samira ghosted Tanvi. Tanvi wondered what had happened. For Samira, it was just a summer fling-that's what she told herself. But for Tanvi, it was more than that. What happens when they end up in the same class, and Samira pretends she's never met Tanvi? How long can she maintain this charade?
