On March 11, AtHeart released the official music video for their new single “Butterfly Doors.”
The track blends a heavy 808 bass line with delicately layered synth sounds, creating a pop R&B soundscape that vividly captures the thrilling sensation of encountering a new world. “Butterfly Doors” is driven by a dreamy and atmospheric mood. At first listen, the song may remind fans of the group’s debut track, "Plot Twist." However, the new single distinguishes itself with a hook built around soft falsetto vocals, offering a different charm from their debut.
The rhythm of the track is also subtly addictive, leaving a lasting impression after just one listen. The combination of immersive production and emotive vocals highlights AtHeart’s evolving musical identity.
Meanwhile, AtHeart will present the first live performance of “Butterfly Doors” at 'Tokyo Girls Collection 2026 Spring/Summer,' one of Japan’s most prominent fashion and culture festivals. The event will take place on March 14 at Yoyogi National Gymnasium in Tokyo, where the group is expected to debut the new song’s stage performance.
