Ako and Komachi are renowned high school twins for their close relationship. They share a striking resemblance with the exception of their hair length, and their academic achievements are nearly equal. However, during their most recent exams, Ako admitted to experiencing a "slump" that resulted in a decrease in her scores. Consequently, Ako has enrolled in remedial English classes taught by Maki Oosawa, the assistant homeroom teacher. Ako shared with Maki that her diminishing academic performance was due to her concerns about love.
