The way each "arc" is handled has become predictable. It's, at the least, easy to read/scroll through. Regarding the romance side, as of chapter 197, there's the "main girl" and a possible new romantic interest. Hardly a harem. I'd say it's easy to ignore. It's not integral to the story and it's not featured that much. Typical OP protagonist, power fantasy with a side of "sci-fi". Don't expect anything more than that.
Edit: Don't get me wrong, I enjoy the manhwa! Just because I said the plot is predictable, doesn't mean you cannot enjoy this. To be fair, OP protagonist stories are predictable in general. Things like the MC being seemingly in a pickle and then "Aha, I've yet to use a fraction of my power" or "I have more tricks up my sleeve!" are extremely common. Also, yay, NO HAREM.
