Shin Adachi, who won many awards including the Japan Academy Award for Best Screenplay for "100 Yen Love", brought his semi-autobiographical novel "Diary of a Loser" to the screen. This film is the first screen debut of Yuuki Ikegawa, a member of the Kansai Johnny's Little Group "Boysbe". It features seven sixth-grade boys in a small town in the late Showa period, and depicts their teenage years full of laughter, tears, entanglements, and challenges. Unlike similar works with a halo and a slightly pale appearance, Shin Adachi confronts youth with an almost frank attitude, which is direct, vigorous, and full of power. Shin Adachi also used the signature long shot of the legendary director Shinji Sayama in the film, paying tribute to this former mentor, and capturing the most vivid and perfect state of the teenagers.
