i feel the same with you. the earlier chapters was good but then hmm...gonna drop this too（￣へ￣）
I just feel like author's lost track of the main plot and ended up on tangent with no clear path path leading back to it, like having arches shows a sense is structure but this isn't it. I guess it just goes to show how difficult it is to make a story, I mean the direction you want the plot to flow will changes as you develop the characters and if you didn't have a very clear plot line from beginning to end then sticking to what you originally had in mind must be so difficult.
I kinda see how some people are calling the MC sloppy and that the way she hopes herself up to be is below expectations but a few things: she's an assassin not a spy, interacting with people isn't exactly her forte.
Everytime she makes any progress in her job, there's the emperor, stopping her from doing what she needs to do by being unprofessional and sulky, giving her side jobs and a new identity and role (being Ba-An)
Then you've got the other two feeling curious enough to interrupt her with the Spanish inquisition and give her their own tasks when she sees them, maybe the fact they catch her in the act is a bad sign on her part, but I don't exactly blame her when she's hardly able to do the one job she was originally assigned with her actual employer and the people he has employed making her job harder without even ay outside disturbance from the rest of the court who might have problem with 'Yesuh'.
Maybe, just maybe she can't do anything we'll cos she can't exactly just go off-grid/under radar with the distractions she faces cos ignoring the emperor will do no good, neither will ignoring either of the silver haired dudes cos they'll just follow her or blackmail her.
Now that I think about it why and how the fuck does the emperor think sulking in front of his court officials with 'Yesuh' is gonna help her do the job he wants from her when he's just salty that she ain't interested, he's hardly helping when Hahae has to go tell the spy candidate that she may have slightly fallen out of favor with the emperor, we want blind adoration to fool the rest so that she can be seen as a real threat not just some girl that the emperor likes for a little while gets what he wants then dips, even a realistic fight between them could be good in faking the act.
He needs to smart thinking with a different body part and actually give a shit or something real stupid is gonna happen it's like he wants everyone to know he hired an assassin, 'Yesuh' had to say some pretty treasonous things to make it seem real that could be used against her. Who's he helping here? Along with blocking her from coming back through the hole after trying to get work done, aahh Im done. ╮(￣▽￣)╭
