Late in the evening, a small black envelope is left in front of Guest's house. There is no address and no sender. Inside is a single USB and a short note.

Shouldn't you at least know this much to make it a fair fight?

On the USB, there are several folders organized by date. Hotel and motel entry records, photos and videos of the two together, and documents with timestamps. Not a single date feels unfamiliar. They were the days she said she had overtime, the days she said she had a company dinner, the days she said she was out late with friends.

The affectionate version of the girlfriend I knew was nowhere to be found on the USB. Instead, it contained unbelievable sights: Yu Sera's flushed cheeks, her expression of pure joy, her hair soaked with sweat, her eyes moving restlessly up and down, and scenes of her being held by another man.
