"Ai o Tomenaide" is the 51st single by J-pop singer Koda Kumi. It was released on September 21, 2011. This was released in three different versions: a CD only edition, a CD only movie edition, and a CD+DVD edition that comes with a DVD of the music videos of the title song and the B-side "You Are Not Alone". The last edition comes with newly arranged versions of her previously released song "Anata Dake ga". The title song is used as the theme song for the movie Second Virgin. The drama version previously featured "Anata Dake ga" as its theme song. "You Are Not Alone" is said to be the national theme or hymn representing hope and a way for Kumi to reach out to her fans and anyone else due to the earthquakes that struck Japan in early 2011.
It was the number one digital single at the weeks of September 14-September 20, 2011 and September 21-September 27, 2011. It was certified platinum for 250,000 downloads in January 2014.
