On May 8 KST, BOYNEXTDOOR released the track list for their debut single 'Who!' The image, which looks like a paper box wrapped with tape, contains the titles of the three songs to be included in the album, including “But I Like You,” “One and Only,” and “Serenade,” along with information on the participating writers.

According to the track list, BOYNEXTDOOR shows strong musical confidence with an unconventional move to present all songs from their debut single as title tracks. Two of these music videos will be pre-released on May 23 and 26, before the release of the sound source, and the last one will be released on May 30, the debut date.

The creative abilities of the members are also outstanding. Jaehyun, Taesan, and Unhak were listed in the credits for "But I Like You" and "Serenade". Based on the music they participated in directly, they will be telling their stories honestly and without embellishment, revealing their ambition to form a consensus with the public.

Producer and artist led by Korea's top producer Pop Time, who produced a number of hit songs such as "Tomboy", "Any Song", and "Move". Zico and Kako participated in producing the debut single. The production team itself has fans excited for this new group, and expectations for BOYNEXTDOOR's music are rising even before the official release.

BOYNEXTDOOR, presented jointly by HYBE and KOZ Entertainment, is a team that freely expresses daily life that friends of their age can relate to through music. On May 30 at 6PM KST, BOYNEXTDOOR will release their debut single 'WHO!'
