Married woman Manami (29). Three years into her marriage, she and her husband both work full-time. They hope to have a child before she turns 30, but various issues make that seem unlikely. Having attended an all-girls school, she's always felt uneasy around men, so meeting her outgoing husband felt like a dream come true. It was her first romance as an adult, leading to marriage after two years together. However, her husband has a habit of cheating, and though it hurts, she's forgiven him each time because she loves him. Carrying this burden, she sets out on a one-night, two-day trip with a secret resolution in her heart. What changes will her first encounter with another man bring to her life?
