the story is ok, but the mc is just so full of himself that it becomes annoying. He also relies a lot on his knowledge from the future so he basically knows everything that is going to happen. I don't think it's very interesting, wouldn't recommend.
His way of revenge has a certain satisfaction to it I have read upto chapter 24 until now it has left an impression and i wanna keep going
this manhwa has a bit of revenge storyline mixed with the second chance storyline and is also not dark(here I mean that some story sometimes gets too into revenge), also the surprise moments when mc shows his skills are amazing, the art is decent and I liked the usage of old knowledge done by mc(not going completely in by changing the future but by slowly using the knowledge)
I also liked the good atmosphere set by the writer despite it being a revenge manhwa and it also gave a similar vibe like a real man or superstar uncle(this is the literal name of a manhwa)
and if you are looking for some manhwa with an mc becoming a successful person by earning huge amount of fame and money then this is the right one
