Yui was totally against her guardian arrange marriage. So she did everything within her power to sabotage the upcoming wedding especially making trouble for those people who's pushing the marriage and terrorizing the bride to be candidates. But then the kings father have enough of her and his stupid idiotic son who spoiled her to no limits. He finally push the wedding and the king can't say no. The king propose to her saying "if you really hate me being married to other woman then me my bride". A proposal that shock her to the bone...!!! Yet an appealing one. She naively think that nothing will change with there relationship but really???!!! Especially when the king father pushing the marriage wanting to have grandchildren while he was alive....!!!
