Yuki Kashiwagi will digitally release her first solo single after graduating from AKB48, titled "I'm not alone," on November 6. 

Written, composed, and produced by KAZUAKI, "I'm not alone" is the theme song for Koji Abe's first directed film 'Old Car ~Tentomushi no Propose~' that's scheduled to open in theaters on November 1. Because the movie was filmed in Kagoshima Prefecture, Abe wanted someone from Kagoshima to sing its theme song, and so, Kashiwagi was invited. 

Starring Show Aikawa, 'Old Car ~Tentomushi no Propose~' is a human drama about a man who loves classic cars.
