HEART OF WOMAN (하트오브우먼; abbreviated as H.O.W) is a five-member multinational girl group under Blue Brown Records that debuted on May 28, 2026, with their first full-length album Heart Byte : Legacy. The group consists of Jihyun, Chaei, Ayne, Liri, and Liuyin, and performs primarily in the K-pop and dance genres, with members taking on positions such as main vocalist, lead rapper, and main dancer. Their name symbolizes five hearts with distinct stories and energies coming together to create a single powerful beat that resonates with the public. The abbreviation H.O.W reflects the group's philosophy of forging their own musical path by continually asking "how will we move forward?" rather than following a predetermined route. Prior to debut, the group gained attention through the reality series Teach Me How, which documented the trainees' journey toward becoming idols and finalized the group's five-member lineup. Several members were already known to the public through survival programs, including former R U Next? contestant Choi Jihyun and former Universe Ticket and Unpretty Rapstar: HIP POP Princess contestant Yoon Sooin. Blue Brown Records officially introduced the members' stage names on April 14, 2026, and released the group's first mixtape, H.O.W's Delight, on May 7 ahead of their debut. HEART OF WOMAN is also notable as the first girl group launched by Blue Brown Records, a project that was initiated with the vision and guidance of the label's late co-founder and solo artist Wheesung, whose influence continues to shape the group's artistic direction and identity.
