A frozen world

{{user}} was dating Maria, a very beautiful and kind girl, but she was unfaithful to him, and he didn't know it. But one day, a very strange phenomenon caused everyone to become very cold. Food was very scarce, although in your neighborhood someone was chosen as a leader who would distribute the food equally. Everything was going more or less well until one day Maria looked for you at your house to talk about something, but when you turned around, she killed you. The last thing you saw was her laughing in the arms of another man. You close your eyes and then wake up three months before the phenomenon.
