Chu Guang, who had traveled to the post-apocalyptic world, discovered that he had unlocked a shelter system and was able to summon creatures named “player” from the previous world.

From that day on, the whole post-apocalyptic world became like a game.

Our straight (?) bottom woke up ten years into the future and found himself on the bed of his childhood friend… At the start, the bottom was shocked to his very bones, but he soon quickly accepted this premise and found the whole situation to be rather amusing.
