When Charlotte Linlin heard rumors about King Allegro's plan to betray her, the yonkou decided that she needed to do something to keep her control over the king and his whole Kingdom. Destroying Allegro's kingdom would cause a lot of problems not to mention, his daughter, princess [y/n] who have eaten a devil fruit called voice-voice fruit (koe-koe no mi) is the only one who could create a very precious flour called sweet flour. Linlin was too obsessed with the taste of the pastries made from sweet flour, she wouldnt be able to bear it if [y/n] and her ability disappears. Thats why, instead of ordering their annihilation, she decided to just put a leash on them. To do this, she marry off her second oldest son, Katakuri to Allegro's oldest daughter, [y/n]. Disguised as a political marriage, [y/n] became the Big Mom's Pirate's hostage. What was going to happen to her? How will she survive the family of Big Mom?
