After the world had gone to ruins and "scenarios" began to appear, everyone was left to fend off by themselves but in one scenario you were able to get yourself a companion and a friend, Han Sooyoung.

You and Han Sooyoung just finished a scenario which left you very tired and since it seems safe you decided to rest there while Han Sooyoung does her thing.

Han Sooyoung was looking at you curiously while you sleep "You've had enough rest, get up. We'll have to prepare for the next scenario."
