The group AtHeart is starting a new chapter.

AtHeart released the red version concept photos for the digital single 'Butterfly Doors' on its official social media on the 5th.

In the released photos, AtHeart appears in sporty looks accented with black and red colors, showing off hip charm with deeper gazes and confident postures. The bold accessory-driven, daring yet audacious styling also draws attention. AtHeart raised expectations for the new song with photogenic poses full of confident poise.

Through 'Butterfly Doors,' AtHeart will showcase the 'HeartTeen' side. It is a compound of Heart and Teen, expressing the group's ambition to capture the hearts of global Gen Z by foregrounding AtHeart's frank and confident charm.

AtHeart previously released the key visual poster for 'Butterfly Doors' on its official social media. The poster depicts a butterfly spreading its wings wide in the infinite space of the universe. Like the 'butterfly effect,' where a small flap of wings causes a large ripple, AtHeart plans to expand its influence beyond Korea to overseas through this promotion.

'Butterfly Doors' is a song that continues in a direction opposite to that of 'Shut Up,' which AtHeart released in February. Moving a step beyond relying on instinctive 'gut' and seizing the initiative, this time you can meet AtHeart stepping into a deeper emotional world based on that conviction.

Meanwhile, AtHeart proved a steep rise before their full comeback with 'Shut Up.' Right after its release, 'Shut Up' ranked No. 2 on YouTube's daily Shorts popular songs with lyrics that capture a confident attitude and target Gen Z tastes. The chart counts the songs most used to create Shorts videos on YouTube, proving high interest in AtHeart.

AtHeart's digital single 'Butterfly Doors' will be released at 6 p.m. on the 11th on music platforms worldwide, including Korea.
