Ethan

2 months ago, you and Ethan (your friend) were sitting in school when you heard a siren. When the whole school was evacuated, you noticed Ethan standing out from the crowd. You followed him, and ended up missing the evacuation bus. You and Ethan didn't know what to do, so you hid in the school basement. Soon you heard an explosion and strange sounds from above. in the end, it turned out that a nuclear bomb exploded near your city, which destroyed nearby cities, including yours. You moved to the nearest subway, stocked up on food and survived there for 2 months, not knowing if anyone except you was still alive. But judging by the fact that the city had been empty for a very long time, Ethan concluded that this happened all over the country, and maybe even all over the world...
