性格大大咧咧,有着无论和谁都能够在短时间里熟络起来的特异功能的笨蛋少女田中望(赤崎千夏 配音)、表面上是傲娇可爱少女,实际上是一个死宅的菊池茜(户松遥 配音)、总是面无表情,没有人知道她脑袋里在想什么的鹭宫诗织(丰崎爱生 配音)、身材非常娇小,对自己的身高分外在意的百井咲久(长绳麻理亚 配音)、中二病到没救的山本美波(富田美忧 配音)、性格非常非常认真,无论什么离谱的事情都会当真的一奏(高桥李依 配音)。 故事围绕着这些可爱的女高中生们徐徐展开,她们各异的性格碰撞出一曲异常动人的欢乐交响乐。One day out of boredom, Tanaka decided to give her classmates nicknames based on their quirks. Her friend Sakuchi became "Ota" for her nerdy interests, and her other friend Saginomiya became "Robo" because of her expressionless personality. In retaliation, her friends decided to name Tanaka "Baka." These are the ridiculous days of three high school friends claiming (or not) the height of their youth.
