So let me get this straight.
Faris agents, including Ceci, smuggled Janes into the kingdom to subjugate the masses beforehand (per opium war IRL) and also to handle key persons of the country. The grand plan is a full-blown invasion, and to smoothen this, Ceci was tasked with approaching the Crown Prince, Enrique, to make sure they have an insider that could handle any cases that go awry.
They screwed up, however, when Sharon, a mere user, gave some Janes to that Scarlet fangirl, who tried to poison Ceci. Ceci's maid, loyal to Ceci's heroine persona, snowballed it into an actual investigation, which put the Gendarmarie in high alert around the royal capital and halted invasion plans. Then somebody, for reasons unknown, planted false clues that lead to the execution of Scarlet, which was not supposed to happen.
With Scarlet executed and both Enrique and Lily sniffing foul play, Enrique decided to marry Ceci for reasons unknown (probably to keep tabs on her and give her children so that she would have legal responsibilities to the Kingdom, I assume). This severely dented Ceci's mobility, and she had to keep taking abortives to prevent Enrique's second plan from fruition, which delayed the invasion for another decade until the political situation stabilized once more for the military to fall into lull once again.
Did I get this right?
