is the 4th single by Japanese idol group Hinatazaka46. It was released on February 19, 2020 through Sony Music Entertainment Japan. The title track featured Nao Kosaka as center, marking her fourth consecutive appearance at this position. The members competed against each other in a Daifugà  tournament for the CD's bonus content.
The single was released in four versions: Type-A, Type-B, Type-C and a regular edition.
The songs "Seishun no Uma" and "Naze" are used in the opening and closing theme, respectively, of the television show Dasada, which casts all members of Hinatazaka46. "Seishun no Uma" was debuted unusually early before the title track on January 11, where it was performed live at a Tokyo Girls Collection event in Shizuoka.
Songwriter Junji Ishiwatari positively commented on the expressions used in the lyrics to describe the singer's love interest, such as comparing her bangs to the art style of Yoshitomo Nara.
