“Nibanme na Boku to Ichiban no Kanojo” (The Number Two Me and the Number One Girl) is a high school romantic comedy manga about an “average” boy and the most popular girl in school.
The story follows Satou Hajime, a plain and quiet student who suddenly becomes known as “Number Two” when another boy with the exact same name transfers in—a handsome, talented ace of the basketball team who is good at everything. While everyone compares him to the “better” Satou, Hajime ends up getting closer to Minamino Chinatsu, a cheerful and beautiful girl who’s admired by the whole grade.
As Chinatsu tells him, “You’re not number two to me,” their relationship slowly deepens beyond simple classmates. The manga explores first love, insecurity, and self-worth through the eyes of a boy who thinks he’s always second best, and the girl who chooses him as her “number one.”
