Two high schoolers, Suzuki-kun and Takagi-san, met in a time loop on August 31st. They are the only ones who can retain their memories when the day repeats itself. A possible cause of the time loop is Suzuki-kun's unfinished business for the summer, a guy's greatest objective... A time loop comedy of youth that tackles love head-on! (Source: Kodansha)
