A secret life is the one thing they have in common. At school, Hori is a prim and perfect social butterfly, but the truth is she's a brash homebody. Meanwhile, under a gloomy facade, Miyamura hides a gentle heart, along with piercings and tattoos. In a chance meeting, they both reveal a side they've never shown. Could this blossom into something new?

When the popular Hori and the gloomy Miyamura meet, they reveal another side of themselves. Could this be the start of something new?

Although admired at school for her amiability and academic prowess, high school student Kyouko Hori has been hiding another side of her. With her parents often away from home due to work, Hori has to look after her younger brother and do the housework, leaving no chance to socialize away from school. Meanwhile, Izumi Miyamura is seen as a brooding, glasses-wearing otaku. However, in reality, he is a gentle person inept at studying. Furthermore, he has nine piercings hidden behind his long hair and a tattoo along his back and left shoulder. By sheer chance, Hori and Miyamura cross paths outside of school—neither looking as the other expects. These seemingly polar opposites become friends, sharing with each other a side they have never shown to anyone else.
