Release Date: April 21, 2026

This album is available in three versions — Hana (One), Dul (Two), and Set (Three) — reflecting the "one, two, three" count found in the lyrics of the title track, "Rock Paper Scissors." The Hana Version highlights each member individually, the Dul Version features duo pairings — Shinwoo & Sandeul, Sandeul & Gongchan, and Gongchan & Shinwoo — while the Set Version showcases all three members of B1A4 together, at their most complete.

After a dazzling 15 years shared as a trio, B1A4 arrive as one fully realized SET — and simultaneously, as the most authentic version of their three-person self. Where the 4th studio album [Origine] laid the foundation of the group's identity, and the 8th mini album [CONNECT] spoke to the bond that endured even through time apart, this album [SET] captures the moment those threads finally converge — woven into a single, complete form. Member Shinwoo helmed the overall production, sharpening B1A4's distinct musical voice and the narrative running through the record.

A story without end — beyond connection, arriving at completion.
From April 21, 2011, the day their journey began,
to April 21, 2026, landing once more on the very same date.
[SET] — the name that marks a new chapter following B1A4's independence.
