That's a shame especially because the story has managed to be very balanced between obvious female interest and good action so far.
I was under the impression that Sophia was just kind & worried from what I saw before the regression, maybe the Manhwa will change some aspects and tune her flirtation down?
Still the story is far too good to just stop bc of Harem although I'd prefer little to no romance (and if anything him to be with the Zero woman) ^^
There are two love interests, Sophia is the most annoying one. The point is there are so much women around MC which seems like a harem. However, nationalistic plot is the bigger problem for me to continue this manhwa, just imagine everyone from every country is useless aside from Korean people (and the best who can compete others easily is the MC of course).
I'm gonna tell you that this manhwa in the further episodes will have more women surrounding the MC. For example, Sophia, the female supporter, she will simp the MC so hard than before regression. It's to the point of making me annoyed her so much, her flirting is so bold and claim to be MC's wife. The MC will tell her with no mind that if she reach 1st place in supporter rankings, he will considering marry with her.
If you read the novel and start to notice women popping out of nowhere near Seong Jihan, let me counting few characters who are very close to the MC for you. There are Ariel, Yoon Seah, Lee Hayeon, Akari. And others that do not, Sophia, Ha Yeonjoo, Ha Yeori.
I still continue to read the novel since the only annoying women here are Sophia and the one who bullied the niece. Also, thhe possible revenge on the Sword Master and streaming function are worth following. It shows how much of the MC influence on public media.
