is that Iveka (FL) is the illegitimate daughter of the Countess, born from an affair she had. Because of this, she faced a lot of discrimination from her family and peers for not inheriting the their beautiful blonde hair. As the Count didn't wish to have Iveka around, he sent her off to attend college where she went on to join the Bureau of Investigation at the age of 18. 4 years went by and eventually Iveka wished to leave her work for unknown reasons. Before she can, however, they give her the choice of being monitored for the rest of her life (to avoid leaks) or to have her memories of the past 4 years erased. For whatever reason, Iveka chooses to have her memories taken. After that, she is approached by Daniel (ML) with a proposal of marriage. Daniel himself is the King of their nation (of which there are several nations ruled by Kings who serve a central Emperor). He was originally a third prince with no desire for power, but the struggles of his siblings eventually resulted in the crown being put in his hands though happenstance. Not wanting that same struggle to continue on in the future, Daniel wishes to take a wife and have a child as soon as possible so that if something were to ever happen to him, succession would fall to his own child rather than another relative.

Though, it's implied (at least in my opinion) that Iveka is E.J, but that she may not remember due to the memory erasure and Daniel can't tell her because that would be a breech of contract. Though I could be wrong. But I feel it in my bones lol.
