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.

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).

JK's toxicity makes me stressful every time and I'm gonna stop reading until the chapter of him and his friends begging and apologizing Dan comes out. Dan doesn't deserve this treatment at all... His financial status, grandma's cancer, loan sharks, and getting hard rejection but still have to be the fuckboy to earn huge money and not gain JK love back, everything is too much. It's rare for me to sympathize the character to the point of stop reading. I must say the author has done amazing job on making shitty character like JK. However, I still want to know what makes him rejects everyone around so far.
From my opinion who already read to lastest chapter of the novel (ch284), please drop this and find something with more quality. This story started interestingly and progressed horribly after that.
Everything centers around MC with the whole humanity tremendously useless to compete in the space league (the league that you have to fight with other species).
Nationalism is very apparent to the point of every country in the story seem bad even its people. For example, at one point later Ito Shizuru will get exposed of her bad deeds from manipulation to murder but... Yoon Sejin who awaken from manipulation skill thanks to Jihan, he will go around to find Ito and live to threaten Japan to bring Ito to him. If not, he will kill hostages every 10 mins. He will get condemned by everyone when his family was fallen apart because of her. Akari (her ninja) will get possessed as her avater after losing to Jihan, her parents also will be murdered by her master. And somehow, at first Jihan and his niece hate Yoon Sejin even they know he got manipulated.
And the chat system or public opinion, this story shows too much.
The niece and everyone just exploit MC. Every point and improvement just pop outs out of nowhere. MC's personality is so bland, I was confused if I am weak to interpret character when I read in English. But no, some people think like me.
Every character has one dimensional personality as well without the sign to improve and the reason. The author just throws information for readers to digest and accept it.
At the moment, I will stop reading this and give only 1/5 since it wasted me 3 days to understand how garbage of this story.
If I have to describe this story in one sentence. It will be 'Nationalistic fantasy story when the world deepthroating the MC and everyone is perfect extras.'
Haven't read the novel but if it is going to be as you say, I just hope they'd change some things in the manhwa
