My wife showed interest in the "calligraphy class by calligrapher Yamaoka Bokusai" held at the local community center. She begged me to go on the weekend, so we decided to give it a try. After that, she started attending Kudan's calligraphy class, which was held on weekdays while I was at work, enthusiastically. But one night, I happened to look at the "collection of my wife's calligraphy works," and felt a strange sense of discomfort when I saw the obscene words she had written, such as "phallus," "penis," and "ecstasy"...!
