Our MC was supposed to get married but caught her fiance and best friend cheating so now instead of being a popular blogger and wife, she is living with her sister, sister in law, and their kids, barely making it out of bed aside from when she helps her sister's party planning business by dressing up as a princess for kid's parties. At the most recent one, she dropped the cake and broke her throne, then yelled at a guest who was laughing at her and ran away when she saw aforementioned former best friend. Unexpectedly, she meets a stranger who sits at her table at a coffee shop and asks her to pretend to be her best friend in front of here finance. The scheme snowballs and now MC is a hired bridesmaid for the wedding, where if then out laughing man from the party is the best man.
