The Survival Story of the Little People Who Traveled Through Time

Live... I want to live... No matter how difficult it is, I will live! It turns out that for me, who is at the bottom, why is it so difficult to survive? New works are released, and everyone's criticisms and corrections are welcome. The protagonist is an absolutely ordinary person. He doesn't have a particularly smart mind or a particularly good personality. He is not a heartthrob type. This is what I imagine will happen to the heroine after she returns to ancient times. Just my own opinion.
