Miu Takigawa views the world from behind the safety of her bangs, content with peacefully passing unnoticed through life. Reserved and timid, Miu struggles to converse with or even smile at customers when at her part time job, but she works tirelessly to support her mother and precious little sister, Haru. It is a shock when a letter arrives from the entertainment company GIP, announcing that she has been chosen as a candidate for their new project. Miu decides to accept the invitation and heads to the meeting spot where the eccentric ensemble of other candidates filter in, all summoned by their own letters. Not long after, the girls are escorted by a manager to a luxurious secret facility, where it is explained that they must follow the mysterious directions of The Wall, whose orders are absolute. The 24th of December, 2016, will see the birth of idols like no other; on that day, the group 22/7 will debut, whether or not Miu and the other members are ready to take the stage.

Teacher Nano Saikawa hasn't given much thought to marriage, but her father's friend wants her to have a marriage interview with his son, Souichirou Takamiya. After the interview, they spend the day together. As they gradually become more comfortable with one another, Souichirou asks for her hand in marriage. Things quickly heat up between them, and the two wind up in bed together. However, when she removes his glasses, she discovers he is not Souichirou; he is actually one of her problem students, Souji Kuga!

But will she be able to resist his charms, especially when her body begins to ache for his?
