The Weakest Man Is Secretly The Strongest

Reborn into a cybernetic world where "synchronization rate" determines everything, I was once a overworked office worker who died from exhaustion. Now, even as the strongest being, I choose to live as an F-rank "trash" who spends his days flirting with beautiful women and enjoying a laid-back life. But trouble keeps coming for me anyway—my ex-wife demands a share of my fortune, my family forces me into an arranged marriage, a brother dies protecting me, and even my own elder brother wants to drag me down with him.

Fine. If you won't let me rest, I won't pretend anymore. One punch per problem—until everyone learns their place.
