堀京子（户松遥 配音）是长相漂亮，穿戴又十分时尚的潮流女孩，在学校里颇有一番人气。可一回到家，为了照顾年幼的弟弟和方便做家务，京子会换上非常土气的居家服，常年不在家的母亲让京子在不知不觉中扮演了代替者的角色，但这样地味的一面，可千万不能让学校的同学们知道啊！ 　　一天，一个 耳朵上打满了耳洞的刺青男敲响了京子家的大门，穿着居家服的京子去看们，让她没有想到的是，眼前这个潮男，竟然是平日里在班上被评价为宅男的宫村伊澄（内山昂辉 配音），原来宫村和京子一样，过着隐秘的双重生活。以弟弟为契机，宫村开始频繁的拜访京子家，两人以他们的真面目相对，心与心之间的距离逐渐缩短。At first glance, the ultra-popular Kyoko Hori seems like a frivolous high school girl, but in reality, she's simple, pragmatic, and family-oriented. On the other hand, the bespectacled Miyamura Izumi comes across as an average, gloomy high school fanboy, but he's actually an attractive young man who has a bad-boy streak and is covered in piercings and tattoos. When these two unexpectedly similar classmates have a random run-in outside of the classroom, a bubbly, sweet tale of school life begins.
