Nagao Kanji (Oda Yuji), who came from Ehime to work in an advertising agency in the big city of Tokyo, walked out of the airport nervously. What greeted her was the smile and nickname of "Maruko" by her female colleague, the returned overseas woman Akana Rika (Suzuki Honami). (In Japanese, "Kanji" and "Maruko" are homophones.) The honest Kanji worked hard and soon got Rika's confession. But he had another woman in his heart. At the class reunion, Kanji met his old classmates Sekiguchi Satomi (Arimori Yami) and Mikami Kenichi (Eguchi Yosuke). Kanji found that his secret crush Satomi was dating his good friend Mikami. He was depressed and didn't know that Mikami was just dating Satomi with a playful mentality. In fact, Mikami liked Nagasaki Naoko (Sendou Akiho), a female student in the medical school. The emotional entanglement of five people, the souls longing for love in the city of Tokyo. Will Kanji choose the passionate and unrestrained Rika, or the traditional woman Satomi?
