Another regressor story, the guy's dream couldn't live up to reality in his first life and he has a second chance at it going 20 years to the past, an already known formula that for some reason is always entertaining, at the start at least... most stories just can't keep it engaging or go high-wire with the cheats and ruin it, for me.
This one has this pointless golden print concept to it, I do think it completely unnecessary (clearly) but it doesn't go overboard with it. so it's bearable so far. Story itself is very standard, it doesn't deviate much of what one would expect of this kind of stories.
The MC is ok, thou he's a bit boring (he's working all the freaking time, if there weren't some FL there he would work all the time), has the appeal of being a normal guy, a mature and hard working one, not a genius or some overly omnipotent type (like "Real Man"'s MC for example), at the same time that's why it's a bit lackluster maybe?
Which brings me to the story, I credit the above more to the story being slow paced while at the same time not explicative enough, it's not clear how the MC does what he does, where he gets his money from for example, it's shown he buys and sells real-state and since he knows the future he does well, but we don't know where his initial capital came from for example, it's not explained how he actually benefits from each deal and so on. On that note, I always find it funny that the MC's in this stories never buy Bitcoin, he went back to 2010, he could multiply his money 10.000 times by the start of 2011, $1,000 becomes $10,000,000... no it's not figurative speech, maybe that's why it's too easy and he becomes rich too easy?
Same goes with his business, I don't want to spoil the story, but there is a certain sense of discontinuity in the story, he's at a pretty basic level and 5 chapters later he's in charge of a major project, it's "sort" of explained but "sort" of glossed over too, classic manhwa/ga concessions, so I'm guessing the novel is better done (if there is one).
Overall, it's an interesting read, nothing great but it's entertaining enough, thou I get the feeling it would work better as a novel.
