In Perpetual Flight Chapter 23

"Where was I last Saturday..." He raised his head, a mocking smile on his lips, "What does it have to do with you?"

My palms quickly broke out in sweat, and I stared at him closely and said, "It's you, isn't it?"

He looked at me in confusion, not quite understanding what I meant: "What?"

I watched his expression, watching for any clues, but to my great regret, he looked innocent and seemed to have no idea what I was talking about.
