In This Extremely Dark World, Can You Survive?

[Second person + multiple heroines + time travel + no system + interaction] Due to some irresistible force, you landed on a strange planet. This seems to be no different from your original world. The streets in the city and the fields in the countryside all look so normal. It's just that... There is no trace of the man. In this world, men are rarer than giant pandas. As for why, haha, you will understand soon. Jie Jie Jie... Anyway, I hope you survive, my friend.
