Since you are talking abour reality, I am sorry, but from one side, the way the Lucie was behaving before the night where she gets
is pretty realistic, the "love elixir" is an excuse the author put in to be nice.
I have seen more than one young woman behave in certain ways in real context, and there was neither "love elixir", nor even being "waisted".
The "love elixir" seems only a bit stronger, and maybe not even, in the dishinibition part than the combination between a recreational environment that makes feel between peers who are actually favouring a certain behaviour, and thus prone to "we all exploring", between friends, and "anything that happens stays here", a vodka red bull or similar combination and a shot (alcohol level above zero but far from waisted), a bit of making her feel special and desired (especially if she feel insecure about herself), a couple of romantic words...
If you notice, effectively the game says clearly the product is ready to go on the market, which means it has already been cleared by food safety authorities, it does not contain any substance considered an illegal drug.
Let's say you try anyway to tell her what to do etc. without any solid proof and just based on a "I don't trust him" or a picture where you cannot even see who is the guy getting the blowjob (as the game says), and that you got in a questionable way that can get you fired.
She is not a submissive or an object - Lucie clearly intends to be neither, think what you do to get her to be interested in you, it is exactly by showing your are not Josh - so she will:
I) send you to Hell straight;
II) immediately feel even more reinforced in the convition to frequent and trust the people you told her not to.
The above, even because there is a good probability she will attribute your actions to jealousy (interpretation preferable for her, because comforting even more her "feeling special"), and feel like "left a Josh for a Josh", and your display of "alpha male macho" will only support that (actually, "alpha males" in animals in behave in a different way from what we tend to indicate as humans, but never mind that part).
If instead you are referring to day 11, the game is clear that the MC suspects something, but does not know what they are going to do, and
.
Scenarios...
I) The MC storms immediately the office of Pascal, threatens/forces him to go to the villa etc. - great, you just ended up your MC in prison for a number of years the moment he storms the office and threatens Pascal, Pascal can continue his business happily
and even if he does not sent you to jail he can ruin completely your reputation and put you down as the crazy guy motivated by jealousy - anything the MC has is something he says he heard around, even the "love elixir" in itself is not a proof, since it was actually.
II) The MC immediately goes to storm the villa - great, he has nothing to do it with,
and there you go again as in case I) prison for years, no damage for Pascal
III) The MC immediately goes to the police - great, what does he do it with, something he overheard that is not sure, the fact Pascal had inside help to buy the company (good, but it can take a long time to investigate and really proof, and in the meantime
)
IV) I get an armed team and storm the place - aside the fact not in every country is as easy to get weapons, especially war-level weapons, as in USA, getting in a fight is a good way to get the police in, and end up in case I, with the aggravating thing of the armed assualt.
This is not a shoot'em up game, let's enjoy the game, without getting too worked up about it
