AMPERS&ONE is releasing special content for fans to celebrate its third debut anniversary. On the 11th, a retro-style third-anniversary plan poster was released through the group's official social media channels. The poster lays out a schedule of content ranging from special events for the group's fandom to a variety of concept photos, an unreleased track, a Q&A and a K-pop quiz, which AMPERS&ONE will roll out in sequence to connect with fans. AMPERS&ONE will release its first studio album "PATHFINDER" on the 17th and kick off full-scale promotions. The album tells the story of AMPERS&ONE climbing toward the top with a humble attitude while blazing new trails and growing. It contains 10 tracks spanning various genres, including the title track "King's Way," and every member took part in making the songs.
