Manga by author Wishroomness - Status ongoing

I wondered if people noticed it, the numbers. It wasn't long before I realized I was the only one who saw them. I found out what the numbers meant when I was fifteen. The numbers that appeared on the neck of every person I met...predicted when and where they would die. I was the only one who knew when someone would expire.But Sehyun was different from the others.He didn't have a bar code.
