The infidelity of Eita Kidous parents led to their family falling apart and made him doubtful about love. He decided not to pursue romance during high school and instead focused on studying to become a doctor. Masuzu Natsukawa, who was tired of being the center of attention, noticed his indifference and asked him to pretend to be her boyfriend. Eita initially refused but Masuzu had one more trick up her sleeve: she threatened to post embarrassing content from his journal online if he did not comply. As a result, Eita found himself entangled in a fake romance with the most popular girl at school. He now has to deal with the envy of his peers and the possibility of receiving a confession.
