In her previous life, she never got to go home until her death. Three years later, she saw her parents again at the base, who were so emaciated from hunger that they looked like unrecognizable people. She was too timid to go up and recognize them, simply because she had no status or survival skills. She could only live a miserable life relying on the team until she died tragically in an accident a few miles away from the base.
Only after she died once did she come to the conclusion that her whole life had been just that of a supporting actress, living for the heroine and dying for the heroine.
In this life, she must go home early and live with her parents in this cruel and cold apocalypse, away from that green tea bitch.
