Yayoi Yanagida, a demure and virtuous married woman, is usually calm and gentle by nature. This year, however, she's suffering from severe hay fever, forcing her to wear a mask at all times. Behind the mask, faint coughs can be heard, and her innocent expression carries a subtle hint of irritation. When a young gardener comes by for work, he's instantly captivated by this unusual side of Yayoi—her concealed vulnerability and quiet discomfort stirring an uncontrollable excitement deep within him.
