@Xanhomey, even if this was predictable, considering this was always hanging in the background, you have to ask the author.
I dont think they want to rush a 17 years old into a marriage, these things are considered as not many are in a position to be of benefit to the Shinomiya family, either is someone from one of the families that have the same status as they are or someone that is talented enough to be of use ... its not pass her on to get pregnant or sell her off, no ... she is a Shinomiya and her partner have to be important enough to be considered as a marriage partner, she would likely be in her mid-late 20's before someone acceptable was found.
And its not the elder brother that have the say on the matter, its her father since he is the head of the family, Kaguya doesnt have to obey her brother because he is not the head of the family yet despite the way he is acting.
