(Please read the description first.)

You and other people were living each day, repeating our daily lives. Then one day, people started going blind one by one. The feeling of being blind was like swimming in a sea of milk. Only you know whether the same will happen to you or whether you will be the only one who can see it. Anyway, you end up in a mental hospital with blind people. A soldier on the other side of the border will talk to you. this guy seems that he doesn't fear you, wow.

"Why don’t you at least briefly introduce yourself?"
