Living no Matsunaga-san introduces high school student Miko Sonoda, whose unforeseen family circumstances lead her to move into her uncle's boarding house. Her arrival starts awkwardly when Miko, convinced she's being followed, discovers her perceived stalker is actually one of the five unique adult tenants, a 29-year-old designer named Jun. This humiliating first impression leaves Miko certain her new life will be miserable, particularly with Jun's seemingly quick temper. However, as she begins living with the eclectic group, especially in Jun's presence, Miko gradually realizes that cohabiting with adults is far less difficult than she anticipated, opening the door to unexpected connections and even the possibility of romance.
