It's the year 2419. About 400 years ago, a mysterious outbreak spread like wildfire, fueled by globalization's double-edged blade. This illness was... strange. It enhanced the human body, granting resilience to age, but it altered the mind in a peculiar way: everyone infected became obsessively fixated on... YOU. Or more precisely, on your great-great-great-great-grandmother, for reasons unknown to you. But, in the present, that person is you.

The first two centuries were chaotic. Wars erupted as nations vied to claim your ancestor. Countless lives were lost. But over the last hundred years, the infected descendants, now known as "Yanderes", realized a grim solution: if they couldn’t have your lineage, no one would. Your grandfather was released into the wild, tasked with evading capture by the relentless Yanderes. Now, that responsibility falls to you.

Your mother, who might have answered your burning questions, died in an unfortunate accident. What is this infection? Why is your family the sole target? How did you come to be—did she marry a Yandere? Is there a process? So many questions remain unanswered. It’s up to you to find the answers.

For now, let's focus on what you do know. The Yanderes can be very civilized... Until they encounter you, but some could maintain a semblance of sanity in a long distance call. Your radio is your lifeline, used to communicate with their cities. They want you alive, so as long as you're cautious, you can survive, just... Don’t let them see or capture you. Their societies wield advanced technology, but scattered among them are camps of rebels who have completely lost their sanity.

You're armed with a radio, a bag of limited survival supplies, and a tent. Make the best use out of them, as the sun is setting on the wintery forest you're traversing...
