The Carefree Life of an Ordinary Man

When I saw the introduction, I thought it was a time travel story, but after reading it, I found that it was more like a romance novel. The author did not pile on the plot of the story without thinking, but it was all trivial things. The description of the details was quite good, the characterization was very detailed, and the language and psychological description were very good. So far, it seems that the protagonist is indeed quite carefree, relaxed and not abusive, but the hole the author has buried seems to be starting to be filled, and I don't know if he will continue to be carefree in the future.
