Girl group Heart of Woman has officially released two bonus tracks as the finale of their debut album promotions.

On the 7th, 'Polaris (Daydreaming)' and 'Life is a game' were unveiled through online music platforms. The two tracks were previously only included in the physical version of their 1st full album, but with this official release, they are now accessible to a wider audience. The group presented this music release as a special gift to the fans who have continuously supported them since before their debut.

'Polaris' was composed by producer OG Parker, who has worked with Chris Brown, Megan Thee Stallion, and Dua Lipa. The song blends 2000s R&B-style drums and synthesizer sounds, conveying a heartfelt message to fans with themes of gratitude and the belief that they remain connected no matter how far apart they are.

'Life is a game' saw composer Ohway! and Hong Hun-gi, who worked on the title track 'Lost in Proof,' participate in composing and arranging to elevate the song's level of completion. Built on an alternative rock-based band sound, it encourages one another and sings of hope amidst an uncertain reality.

To commemorate their 1st full album promotions, a special clip for 'Life is a game' titled 'The Most Beautiful Moment' was also released. The video captures the members' growth from their time promoting in the United States to their debut and 1st full album activities, meaningfully emphasizing the time spent together with fans alongside the music.

Since their debut, Heart of Woman has released a full-length album and established their own distinct musical color and narrative through the title track 'Lost in Proof' and various other tracks and music videos. By featuring a title track with Korean lyrics, they revealed an artistic identity that transcends language and borders. Their first full album ranked 15th on Billboard's 'Best K-Pop Albums of 2026,' earning recognition for their global musicianship.

Looking at the members' individual careers, Jihyun appeared on JTBC's 'R U NEXT?', Chaei on SBS's 'Universe Ticket' and Mnet's 'Unpretty Rapstar: Hip Hop Princess,' and Ain on Dingo's 'Killing Voice' for Wheesung's episode. Heart of Woman is the first girl group under Blue Brown Record, a newly founded label established by the late Wheesung and Chief Creative Director Myung Sang-woo.
