I jokingly told my childhood friend "I like you," and now I can't escape from it.

A third-year middle school girl named "Haru" has an adorable same-sex childhood friend named "Chifuyu." To Chifuyu, with whom she had been close since long ago, Haru began to whisper things like "I love you" and "I adore you" at every opportunity. These were "false words" filled with affection, devoid of romantic feelings. However, Chifuyu harbored and nurtured "different feelings" in response to Haru's whispers. This is a story of two girls and their feelings toward such words――.
