It Takes TwoCHEMISTRY
The title track from the single “It Takes Two / SOLID DREAM / MOVE ON,” released in November 2002.

The song was used as the theme for the drama “Double Score” and reached No.
1 on the Oricon Weekly Chart.
In 2008, it was re-recorded with a more lyrical arrangement after being selected by fan vote, cementing its status as a long-loved track.
