Chitose visits her best friend's house as usual, venting about her cheating husband. But today is different—her friend has gone out to work, leaving Chitose alone with her son, Kota. Shy and easily nervous around women, Kota suddenly becomes aware of his parents' sexless marriage and finds himself paying more attention to Chitose than usual. When Chitose casually brings up love and relationships, Kota awkwardly opens up about his romantic struggles. Though clumsy and hesitant, his honesty becomes the spark that stirs something deep within her.
