After killing the Demon King and returning to Earth, the world was in chaos due to the gates. Now, I just want to take care of my people and live as I please. After all, there’s no hero party here to oppress and bind me.

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. Precisely then, the bottom once again went back to his timeline — back to when he and the top were just platonic childhood friends.
