Transmigrated As The Original Hero In A Game-Like World

He watched it all go to hell.

The hero of the story is supposed to have it all; fame, respect, money... women.

At some point he did. He had everything he'd ever want in life, up until he didn't.

With his last breath, he commits a ritual to replace his soul with another just to escape his life.

And as such the new Kieran transmigrates into the body of the original hero after leaving a scathing review.

But he awakens with a powerful trick up his sleeve; he knows the plot, knows the characters and most importantly he's not an idiot.
