She as the third daughter of the marquess family, did not have a fiancee yet, but later in the story, the crown prince of the other country, decides to have an engagement with her, with the reason of forming an connection between the two countries, but the thing is that even FL said: why her? kinda, cause there are other families much more powerful than hers so another reason its love. The problem is it doesn't tell the ML's reason of why he loves her... meh, which is annoying.
