Idol girl group cosmosy has launched their official debut single, “Lucky=One,” featuring a vibrant fusion of tropical house and energetic pop. Following the phenomenal success of their pre-debut track “zigy=zigy,” which racked up more than 10 million views in just two weeks after its December 31, 2024 release, the group is now fully embracing their moment in the spotlight.

“Lucky=One” is all about love arriving as a happy coincidence that blossoms into destiny. What starts as a lighthearted connection gradually deepens, and the presence of each other becomes increasingly precious. The lyrics express more than just chance, they capture that yearning certainty that two souls are meant to be. Rooted in tropical house, the track features smooth synthesizer sounds and a gentle melody that brings out the song’s warm emotions. The rhythm flows softly and builds over time, adding depth to the feeling of love and gradually drawing the listener in. Delivered entirely in English, the song conveys a refined and sophisticated sentiment that leaves a lingering and powerful impression.
