It's called EYESEX.
I had this random daydream where I bump into Alex and Sherry on the train station. We rode the same train and turned out that they'll be off one station before I do. So I sat beside Sherry, who was beside Alex, and we talked about many many things, from our lives, why they're here (no longer remember the reason.
), Then I took a photo of the three of us with my phone. Then once the signal for my stop came, thoughts were gone.
