Maria Morizono is a 26-year-old accountant at Tsuda Confectionery, where she works as a mid-career hire in the accounting department. She is known around the office as the company's secret advisor, a reputation earned because she always seems to know everything and offers perceptive, helpful guidance to her coworkers in her own quiet way. Despite her composed and reserved exterior, Maria has a deep passion for sweets; she runs an anonymous snack review account on social media that has gained a considerable following. This secret hobby reveals a lighter, more enthusiastic side to her personality that contrasts with her usual professional demeanor. Within the story, Maria serves as a supporting character and is a junior coworker to Masugu Tateishi, the male lead, working alongside him in accounting. Her role often involves providing subtle assistance or unnoticed interventions that help the main characters navigate their secret workplace romance, though she rarely draws attention to herself. Maria’s key relationships are primarily professional, though her quiet observational skills allow her to understand the dynamics around her more than most. Her development is subtle, gradually revealing the depth of her knowledge and her genuine care for her colleagues, while her notable abilities include exceptional problem-solving instincts, a knack for giving sound advice, and a vast, encyclopedic knowledge of confectionery.
