BLACK DIAMOND's latest work was written by member ANRI. 'Once, there was a day in me when the light for my dream was about to go out.Corona is also waiting for her, raising her hand many times and disappearing fragments of dreams.What I want to leave in this world is proof of life, a sincere wish, and a song that people hope for.I think everyone lives with various conflicts. But if you don't lose hope and believe in it, you'll never!I can't believe the day will come when I write lyrics to sing on ZEPP!!"I thought this ""I'll Shine"" was a ""miracle song"", so I wrote the lyrics." (ANRI comment) "I'll Shine = I Shine" has completed a song that predicts their future success!!
