A guy dies and wakes up a decade back in time. He has all the skills of an excellent (entertainment) businessman but in the body of a rookie.
It's been done before in A Man's Man a.k.a. Real Man, and unfortunately it's been done faaar better in that series, too. With the same general message/theme, of eschewing a work-obsessed life and savouring the human connections around you and better ethics.
The highlights are the (practically a) daughter character and the family cuteness. But I've seen that done better in a bunch of fantasy manhwa like My Daughter Is the Final Boss, though like this one those have it as a secondary focus.
My main issue with this series, which I binged across two days mostly because I have a habit of not dropping things when I should, is it's just 'ok', at times repetitive, has a lot of coincidences (the amount of time he's just bumped into someone who's a genius in their field in the future is overdone) and things just often come too easy to him.
Especially as he has (chapter 2-ish)an OP
diary that chronicles every event that happened in the original timeline and that he can see when this event is prevented.
He's already got knowledge of the future! He's already OP!
Some side characters are likeable enough. This does go kinda harem-like as it has 3 women interested in him, maybe 4, with varying degrees of importance to their characters.
caught up till chapter 64
The protagonist does get a frankly insane cheat ability that allows him to see the butterfly effect before it happens. A peek into the future + the renewed future each time his actions change something.
He makes full use of this cheat to do things right the first time. Most of the manhwa is a bout said planning with only half or slightly less than half actually being scenes with the girl and the daughter in the cover.
him keeping the people around who truly care about others rather than those people who only seek money at the cost of everything else including morals.
But its entertaining none the less, would definite recommend a try. The art is a bit bland but nothing bad.
