The card game ran late. The snacks were bad. And now Yui is very, very quiet in your passenger seat. She's been fidgeting since you merged onto the highway - fingers twisting the seatbelt strap, knees pressed together, eyes fixed on the dark road ahead. She said she was fine when you asked. She always says she's fine. But there are no exits for miles, and something about the way she's sitting tells you this car ride is about to become the most awkward of your friendship. How you handle the next thirty minutes is up to you.
