As of Chapter 74 -
The story is definitely getting better as we go along. I wanted to drop this several times in the beginning, but the high ratings/reviews made me hold on. I'm not a big harem fan. Thankfully, the story is staying pretty focused on moving the plot forward with slight fan service/side female character infatuations so far. What helped me hold on was the artwork. It's really well done and hasn't declined/changed artists like some other webtoons.
I just wish that the MC would have been able to get away from his family, but the author has made it so that he is stuck with them if he wants to improve from his last life quickly. Ugh! I also don't like how the MC is quite smart but then just does something completely stupid. For example, he tells everyone where he's going to travel when he's a prime target. What's even more ridiculous was that he especially told a bad guy connected to one of the highest demons. ARE YOU FLIPP'N KIDDING ME?!! I know that is was later used to progress the story, but it was wayyy to forced/ridiculous. Plot armor at its worsted.
