Iroha Igarashi, the prettiest girl in high school, is mistaken for a shoplifter at a bookstore but is rescued by Hikari Tsutsui, a hardcore otaku who loves 2D anime. The next day suddenly asks him to be her boyfriend. Although he is wary and wonders if he is being bullied in a novel way by someone who "has a life," he reluctantly agrees and the relationship between two completely different people begins.
