Rinko Amaki is a successful 27-year-old woman who works at a busy wedding planning agency. She excels at her job to such an extent that she is promoted to lead her unit. She is popular, beautiful, and hard-working, but there is just one thing that frustrates her: Despite being surrounded by loved-up couples and romance all day at work for years, she is still single.

The duo, having discovered they share the same “problem,” decides to do something about it. But they soon discover that work and physical intimacy are not easy to balance. And while they might have initially envisaged a quick and fuss-free fling, Cupid might have other plans for them..
