At a high school entrance ceremony, high school student Aihara Kotoko, who isn’t that smart, notices pretty boy Irie Naoki. She falls in love with him immediately. Kotoko initially doesn’t express her feelings to him, but finally has a chance to tell him how she feels. Unfortunately, Naoki turns Kotoko down, saying “I don’t like dumb women.” One day, Kotoko’s house is severely damaged by an earthquake. Until the house is rebuilt, Kotoko Aihara and her father decide to live with her father’s friend. When Kotoko moves to her new temporary house, she is surprised to learn that Irie Naoki lives there as well.
