The book that my pure and modest childhood friend had was unexpectedly a boys' love novel...

Kaede was born into the Tsukimizato (Yamanashi) family, which values discipline and history. From childhood, she was raised strictly and forbidden from all contact with worldly things such as television, games, manga, and smartphones. However, one day, her childhood friend Yoshinori catches sight of Kaede secretly clutching a small package... An outlandish romantic comedy delivered with unpredictable developments guaranteed to bring roaring laughter makes its grand entrance here!!
