Misaki Yoshioka is a thirty-year-old marriage consultant who believes a marriage partner should be chosen through matched requirements, relying on data and logic above all else. Her colleague Kentarou Suda, who joined the company at the same time, is a romantic who prioritizes compatibility and emotional connection, insisting that love is essential in marriage. Their opposing views lead to constant clashes during work. One night, while discussing their outlooks on marriage, Misaki remarks that physical compatibility is one of the requirements for a successful union, but she never expected to end up sleeping with Suda. This unexpected physical involvement forces the two data-minded realist and idealistic romantic to test whether a relationship with apparent zero chemistry can actually lead to a meaningful marriage. Their personal and professional boundaries blur as they navigate the contradictions between their philosophies and the undeniable attraction developing between them.
