Missing From Nowhere

It's fairly easy to say that Nowhere is not the most original name. In fact, people make jokes about the founders lack of creativity quite often. Still, all residents of Nowhere harbor a love for the land, where everything is safe, calm, and nothing terribly out of the ordinary happens.

That is, until the 365th day. Nicknamed that way, not because of its actual place on the timeline regarding Nowhere's history, but because that day 365 people of the population of Nowhere woke up with a tattoo on their arm saying, '365'. That day, one after another, everyone marked disappeared. The rest of the population had different numbers, and it took little brain to see what was happening, especially after a cryptic message was tattooed on everyone's other arm. 'Find number 1'.

Pasts are revealed, and drama ensures. Who is the resident with '1' on their arm? And what is the real purpose of Nowhere?
