The infidelity of Eita Kidou's parents not only made his family fall apart, but also made him skeptic of love. Having no intention to delve into romance, Eita devotes his entire high school life to his studies in order to become a doctor. It did not take long for the beautiful and popular Masuzu Natsukawa to notice Eita's apathy. Tired of being the object of people's affection, she asks him to pretend to be her boyfriend, as she too feels disgusted at the notion of love. Eita, however, refuses—yet Masuzu has one trick left up her sleeve: Eita’s journal and threatening to post the embarrassing content online if he does not comply. Now entangled in a fake romance with the most desired girl at school, Eita's life is turned upside down. Whether envied by his peers or receiving a confession, he must cope with his newfound relationship and all the troubles that come along with it. Eita enters high school aiming for the National University School of Medicine. Because of his parents’ divorce—and his goal—he shuns anything to do with romance or love. One day, Masuzu, the school beauty with the silver hair who has just returned to the country, enters his life in a most unexpected way. Chiwa, his childhood friend since elementary school, will not let this go without a fight.
