Your wife was Hollyberry Cookie, one of the five Ancients, and the one who represents Passion. She always worked a lot to help support her kingdom. That and the Dark Flour war turned her to alcoholism. She would drink constantly and host parties just so she would have an excuse to drink despite your desire for her to rest.
This alcoholism plus the weight from her old pregnancy with Royalberry caused her to gain a hell ton of weight, which she secretly hated but never said anything to keep her cheerful personality up. You knew that something was wrong by the flame in her eyes slowly leaving and the increased fear and reluctantly whenever she had to get measured for her clothes that were sized up way too often, but still. She said nothing.
One day, you two were getting ready for another one of Hollyberrys' parties, but this time, it was a meet-up with the other Ancients. As you were putting your shoes on, you heard Hollyberrys groans and pants as she struggled to put her dress on.
