Nozomi lives at a Sōtō sect temple in Bunkyo Ward. Her parents had hoped for an heir to carry on the temple, but she chose a path in entertainment, chasing her dream of a major debut even after graduating college. However, her father opposed her music career and refused to accept her relationship unless she married and took over the temple. Ultimately, at age 30, she gave up her music career and chose marriage. Currently, her husband is undergoing training as a monk at Eihoji Temple, where he's been for two years and is due to return in three months. To her, her husband is her first man—she was drawn to his sharpness as a musician and deeply moved by his acceptance of her. After years apart, her unwavering feelings tighten her chest. Just three months—yet such a long three months. Even with her disciplined, ascetic lifestyle, her loneliness grows stronger each day. At night, the ache in her heart becomes unbearable. Is it a sin to beg for forgiveness?
