It's "villain wasn't born, they are made" again.
But the author did a damn great job at stretching it into a deeper lore than just simply like 'heroes from another world summoned by a kingdom that's actually corrupt and the real villain'.
2nd chapter and it's already feel too repetitive. It's basically almost copying the script for 1st chapter. The supposed hero wasn't even shown to have any notable contribution except showing up and snatching a girl again.
