Subin of Cosmic Girls returns as an OST (insert song) singer for the first time in about 7 years. The OST Part.01 'Today is a Day to Laugh,' sung by her, will be released today (16th) at 6 PM through various music distribution sites. 'Mari and the Changed Dads' is a drama that depicts the birth of a family that is thicker than blood and tenaciously different. It tells the story of the daughter Mari and her three dads reconciling through conflict, finally being reborn as a true family, starting from a pure desire to have children. The first OST of the drama, 'Today is a Day to Laugh,' is a song that highlights Subin's powerful and refreshing vocals, beginning with beautiful piano sounds and featuring a colorful composition with a splendid string line and chorus. The hopeful lyrics convey the story of family beyond the protagonist's love, such as 'Today is a good day / It feels like a dream, such a good day / Searching for happiness hidden in the day / Let's walk together.' Subin debuted as Cosmic Girls in 2016, serving as the main vocalist, enriching the energy and fantastical melodies of the songs. In 2023, she made her musical debut in 'Aloha, My Mamas,' showcasing her solid singing ability and delicate, three-dimensional acting through 'Great Comet' and 'Burn the Witch,' demonstrating her presence on stage. She has been cast as the lead role Mari in the musical 'Marie,' which opens on December 20, continuing her active career. As this is her first OST singing since the 2018 SBS drama 'Love's Instructions - The Love Diary of Hunnam and Jung-eum' with the OST 'Slowly,' expectations are high for how she will captivate viewers with her sensibility.
