1 Room Apartment + Highschool Girl Suddenly Living Together? Close Contact!? First Sex!!?

Misaki Akane is a high school student accustomed to living independently, as her parents are constantly occupied with their demanding careers. Seeking a place of her own, she rents what she believes to be a private room, only to discover a critical error in her lease agreement. Due to this contractual mistake, she is forced into an unexpected and highly awkward living arrangement with Hazama Ken, an ordinary salaryman. With no other options available, the two must share the cramped one-room apartment until another unit finally becomes vacant. The close quarters immediately blur the boundaries between strangers, turning everyday routines into a series of tense and intimate encounters. Neither Misaki nor Ken could have anticipated the challenges of cohabiting in such confined spaces, where every interaction carries an undeniable weight. What begins as a frustrating administrative oversight gradually shifts into something far more complex, as proximity breeds familiarity and unspoken tension fills the small room they now share. Unbeknownst to both of them, this accidental arrangement serves as the unlikely foundation for a profound change in their lives. The initial discomfort of their forced cohabitation slowly gives way to an unexpected romance, transforming a simple housing error into a deeply personal connection that neither the young student nor the working adult ever saw coming.
