Whispering fate (BTS Taehyung fanfic)

This is a ROYALTY AU story from my imagination and has nothing to do with any person mentioned in this story.
Well, I am not 100% sure on the description of the story though I have a plot planned out. So....I will sort of give the intro to characters here:
Namjoon and Taehyung are both sons of the great king Seojoon and the just queen Yeji of SECOS kingdom , who have retired to peaceful life away from the throne to the summer castle after handing over the crown to their son, Namjoon, who was fixed to marry with an ally but fate had other plans as King Namjoon fell in love with a man named Seokjin,his so called arranged fiancé's brother. This was a huge shocking blow to both the kingdom's and Seokjin's parents disowned him and took away his title of crown prince of AZOV kingdom. It was an devastating moment for both the kingdoms as it was not just a shock but also doubt about the heir but the people of SECOS decided to support the love of their king Namjoon which helped a lot in his marriage to his love who became the queen Seokjin of SECOS.
It was decided that the crown prince Taehyung would be the one to provide the heir to the throne and the officials began suggesting their own daughters for the hand in marriage to fulfil their own plans for their future. The Queen mother Yeji one fine day suddenly made an announcement about marriage of her younger son to a common girl, which was first met with disapproval but well no one can deny the Queen mother and her tactics.
Crown prince Taehyung is set to marry a girl he has never known least loved without a say or his consent in the matter,which has him enraged but he knows that he cannot deny his mother so decides to get the girl to deny it by bribing her to deny it or if nothing works even to threaten her to deny it............
Them and the rest of the characters are properly introduced in the start of the story.
The ships included are:
Taehyung +y/n
NAMJIN
KOOKMIN
SOPE
Hope you enjoy it.....
