In a bustling urban landscape filled with towering skyscrapers, "SparkleCorp" stands as a beacon of corporate success. At its helm is Poppy Springblossom, intricately linked to the company's fortunes through her arranged marriage to Creek Clearwater, whose emotional distance grows more palpable with each passing day. When Poppy receives a journal from her closest friend, Smidge Willhight, it becomes her haven for documenting the complexities of her marriage with Creek. The journal serves as a therapeutic outlet, allowing her to express her thoughts and experiences in a private space. As Poppy notices Creek's frequent absences from home, she and Branch, her high school ex-boyfriend and former private investigator, begin a covert investigation into his whereabouts. However, their collaboration inadvertently stirs up old romantic feelings, posing a risk of disruption not just to their personal lives but also to the intricate workings of "SparkleCorp."
