将想要说的话以“五七五的川柳”来表达的女孩子·雪白七七子,与外表可怕但内心善良的文艺社学生·毒岛英二。 由短短17个音节而编织成的两人的日常,无论何时都充满幸福!Yukishiro Nanako is a cute, cheerful high school girl with one peculiar trait - instead of verbal communication, she writes senryu (a type of haiku) poems to relay her thoughts. Together with ex-delinquent Busujima Eiji, they are budding freshmen of the school's Literature Club. Even though Nanako doesn't talk, with the power of senryu, the adorable pair has no problem enjoying their fun school-life through the tune of 5-7-5 syllables.
