The MC ends up being a Jap harem-protagonist virgin retard. And this isn't saying: "oh boy I wished he'd fuck everyone", but that every time a girl hits on him, or teases him, he covers his face and runs away. At a particular scene, that wasn't even an exaggeration. He covered his lips, and shied away from the woman who teased him. The MC is consistently pig-headed and acts like a clueless 12 years old. His constant reaction to females, is either not understanding why females react so "strangely" around him, or to be a helpless virgin.
That means the "romance" is absolute dog shit and terrible and should always be skipped.
Other than that, the author tried to hype up the story way too much. The MC partners up with level 5s and 4s almost immediately, and that made the MC rely on plot-armor and "lucky breaks" to survive at the end of the day, because there's no way, even for the strongest level 1 newbie, to survive these sort of high-level missions without the author stepping in and saying otherwise. It just feels disgenuine, like a lot of other shitty webnovels.
I dropped it at around chap 100~120 or so after the author got so clueless with what to do with the story, that he just farted a random tournament-event of some kind. Now THAT'S something I saw a lot in Chinese stories.
