Does anyone know the name of this webtoon?

It's about a guy that either gets sucked into or is reincarnated into a medieval world based off a video game or book he knew in his original life. And he gets reincarnated as maybe a duke's son and the character is super lazy. But the MC decides to change this because he knows what happens to this son as the story progresses.

And he gets like skill points that he can upgrade into and there's a narrator sometimes. The other characters are shocked at the sudden development and change of the duke's son and some are super suspicious?

There's a plot where the MC gets the duke out of extreme debt over fertile lands or something?
