Late in 2009 a group of youths were abducted and imported to a secrect lab. That's it. That's all people know about the strange abductions. But some people know what others don't. Like, the children were named by numbers. Like 1 or 2. And that they were forced to get tattoos on their wrists of their number. But only one person knows that the teen that escaped in 2017, was number 3. Or, Kim seokjin. And was later discovered by a teens about his age.
