Energetic teenager Shuichi Shindo is the lead singer and songwriter for the smash-hit pop band, Bad Luck. He recently moved in with his older lover, Eiri Yuki, the handsome, sophisticated, and uber-famous romance novelist. Nothing goes smoothly for Shuichi, however.

Yuki is inexplicably cold and cruel toward him, more so than usual; he can't come up with new lyrics, due to a bad case of writer's block; and he's entered, totally unprepared, into a nationally televised concert contest with Bad Luck's rival band. In this often touching, frequently hilarious novel based on the popular manga and anime, Gravitation is about two lovers who defy all the odds.
