K-pop girl group Kara recently released a new song titled "Hello," which is a ballad about the emotions of meeting someone new and saying goodbye. The song is part of their upcoming digital single album, "I Do I Do," set to be released on July 24. The agency RBW revealed that the song was originally intended for the group's fourth LP in 2013 but is now being released with Goo Hara's recorded voice, who tragically passed away in 2019. Goo Hara had previously released the Japanese version of the song on her solo single "Midnight Queen" in November 2019. Kara, which debuted in 2007, disbanded in 2016 but made a comeback in 2022 with a special album to celebrate their 15th anniversary. The group's agency also provided information for those in need of mental health support, urging individuals to contact the Ministry of Health and Welfare's helpline if they are struggling with thoughts of self-harm or suicide.
