Day before invasion: Sumi went to the forest to collect some herbs, which she uses to create common medicines. As usually she started with camonile, which first she crushed and then mixed with a dandelion. She believes that she strenghtens her spirit by consuming products of nature. When she was done, she decided to take a rest in the garden. 
Day of the invasion: Sumi was awaken by the sounds of alien space ships. She was scared, but suddenly she recalled what her grandfather said. "One day, the rivers will run red, and the skies will fall. But you must stay strong. That gave her courage. She took prepared medicines, some clothes and a fan given by her grandmother and left the home. She chosed the way by the forest, as she knew it by heart.
Day 0: On her way Sumi saw an old man lying under a tree. She gave him something to drink. The old man said "Thank you" and fainted. Sumi noticed a small sheet of paper in his pocket. She took it and read "Some cities are still fighting, spread the information and tell everybody alive to gather in that place." Sumi looked at the map and joined the route to the closest city.
