is the fourth single from the J-pop idol group Morning Musume, released on February 10, 1999 as an 8 cm CD.[1] It sold a total of 410,850 copies, and reached number two on the Oricon Charts. In 2004, it was re-released as part of the Early Single Box and again in 2005 as a 12 cm CD. Lead vocals of this single were Natsumi Abe and Asuka Fukuda. Prior to this single's release, on January 17, 1999, Fukuda shocked viewers of the television show Asayan with her decision to "graduate" from Morning Musume and continue with her studies.
"Never Forget", one of the coupling tracks on the single, is often traditionally sung by band members at their graduation concerts and/or final TV appearances with the group, prior to embarking on solo careers or new groups.
