This work was created last year, 2022, when NIHA-C was listening to TORAUMA's music all the time, and when he heard TORAUMA's song "Sol", he couldn't stand still! The production of this song started when NIHA-C impulsively called TORAUMA and said, "I want to write a song! The song is about the various problems in life and the constant search for answers to these problems. How can I be happy? What is the purpose of music? The lyrics are based on the actual experiences and feelings of TORAUMA and NIHA-C. It is a song that listeners can project onto their own lives and move forward with them, even if they are still struggling. The beat is by SEESAW, who is also known for the beat of TORAUMA's viral hit "TSUBAKI".
