High‑school senior Kotoko Aihara was forced to give up her virgin heart forever to Naoki Irie, the school"s superstar. For two years the girl in love had been fighting hard to get into the coveted Class A where her beloved studied, but she ultimately remained stuck in the school"s swamp. Frankly speaking, she is a good person, but it just isn"t meant to be… The final graduation year arrived. Desperate, Kotoko poured all her feelings into a love letter, but Naoki publicly refused to read it, declaring that "his idiots don"t interest him." The poor girl realized her life was over… And then the new Aihara family house, clearly built by a single dad who saved on materials, collapsed in a weak earthquake. However, when Kotoko learned she would have to temporarily move into her father"s old friend"s house—some "Iri‑tana"—she was already indifferent… Now guess who welcomed the unexpected guests at the threshold of their new home? And how will Kotoko"s co‑living with her boyfriend, his good‑natured father, the overly meticulous mother, and the gloomy younger brother end?
