What are you talking about ?? Kylie's
one of the few characters who figured that out on her own... we can blame this on her habits as a successful, workaholic and well-connected lawyer, she then told Gabriel, her and Afina's dad, and Afina only knows the MC is that kid who used to come play with her brother, not an undercover cop risking his ass out to take down a dangerous criminal organization he suspects killed his mom.
The second one is Vanessa, MC's childhood friend, who seems to be a very skilled hacker pretending to be part-time twitch streamer or just a very passionate gamer girl. She specifically let him know of this and how she saved his ass by covering for him on more than one occasion too.
It seems like she spied on the MC and tried to protect him from a distance as much as she could for a long time, probably from those criminals she ended up working for for some reason, judging by the pic of him and Tianna on her monitor, but except them, that's it.
No other LI, side girl, or woman he comes in contact with so far, Tess and Sarah included, knows about the MC's undercover mission, unless you count the principal on the love/fuck interest list too lol.
The story's clearly not perfect, no story ever is, but it's not
that bad either.
Matter of fact, it barely started unfolding. If it's not making too much or any sense so far in certain aspects, it's most likely bcz we don't have enough information to judge that for sure, but future updates will shed light on these certain aspects. Plus, the game's a big ass work in progress until it gets the completed tag, things can and will oviously change for the better.
I repeat,
not a single young character the MC interacts with so far knows him, not even Afina and Kylie were sure he was that kid who used to hang out a lot with their brother, with them too occasionally, even after he told them, only the older ones do, the ones who also don't know anything about his undercover mission, and they're disappointed he didn't keep in touch with them for so long, for obvious reasons.
Not only this, the MC himself doubts his decision to come back and go undercover on a few occasions in the story. The guy has critical thinking skills and potential for this type of work, he's far from being a cookie-cutter harem porn game fuckboy cliché.
That temu wannabe Chinese Triad boss, Zhao, even commented there was no information or compromising stuff on the MC they could use to their advantage. Don't know why this is even a debate, when it's specifically stated in the story, ffs. Proof in the spoiler tag bellow...
And there are a few characters constantly reminding the MC of the
severe consequences of his actions in this line of work, especially in a situation like his current one, characters like Tianna and Sancho do it on many occasions, then Gabriel, Kylie, even Vanessa make it abundantly clear his mission is not to be taken lightly... if shit does go south, it's his own ass and those of the ppl he cares about on the line.
So again, I don't know why what's obviously shown or stated still needs to be debated, but guess some peeps missed a few important parts in the story just to get to the good stuff, or to see how much content there is in this update, or something.
