First impression, this is first impression as it's not yet pass 50 chapters. Okay, here we go: ------ It's start with a confusing story, and evolve to a kinda interesting story, to an interesting story. I don't know about every one but, for me this is unique. Like, what's happen in his original world, and how he transferred to young man's body, and how he tell, with honesty, to the original man's family, that he is not the original man, and more to that. Also at first I would expect the story would involves around s*x or something like that. But it's not like that at all, there's not even one tiny bit of hint that the MC would do something like that, yet. Well, I think from what the story tell us, it is for sure would lead to something like that, we just don't know when... it can be soon enough, or can be at a really future chapter (around 100ch - 200ch) as the story flow in this novel is slow paced.
