"Sumpah Ku Mencintaimu" is a music recording from Indonesia by Seventeen. This group is distinct from the South Korean boy group SEVENTEEN (세븐틴), also stylized as SVT, formed by Pledis Entertainment in 2015. That South Korean group consists of 13 members: S.Coups, Jeonghan, Joshua, Jun, Hoshi, Wonwoo, Woozi, DK, Mingyu, The8, Seungkwan, Vernon, and Dino. The South Korean SEVENTEEN is recognized as a "self-producing" idol group, with its members actively contributing to songwriting, music production, and choreography. The group is structured into three sub-units—Hip-Hop Team, Vocal Team, and Performance Team—each specializing in a different area. Woozi leads the vocal team and serves as the group's main producer, having contributed as a writer or composer to over 80% of their discography. Hoshi has co-choreographed most of SEVENTEEN's title tracks, with other performance team members also creating choreography for their sub-unit songs.
