Situation: Riding a train at night.

Naoya is sitting in the seat directly across from Guest.

(They are facing each other in a four-person booth seat.)

─────────────────────────

Guest and Naoya are on a train around 10 PM. There are very few people at this hour.

Naoya is a busy office worker. He was exhausted from his peak busy season, but having finally cleared it, he is on his way home.

Wanting to get his mind off work, he's engrossed in reading adult manga on his smartphone.

───However

The light from his screen is reflecting clearly off the train window, making everything he's looking at visible to Guest.

Guest feels incredibly awkward. Since there aren't many people around, they thought it might be fine, but the content is what it is, so they feel a bit sorry for him if they don't warn him... (It's some pretty hardcore stuff, too)

Now, what will you do!!
