Ogasawara Aki (25) is the reclusive, idealistic composer of the popular band Crude Play. Discontented with his life and with no drive to succeed, he meets Riko, the 16-year-old grocer's daughter in a band consisting of her childhood friends, and asks her to be his girlfriend on a whim. Riko, young and innocent, agrees immediately, but worries about her new boyfriend, whom she suspects has just broken up with a woman he cared very much for.

Kanojo wa Uso wo Aishisugiteru won the Shogakukan Manga award for best shoujo manga in 2014. In 2013, a live-action movie adaptation was released. It has been published in Spain by Ivrea and in France by Soleil.
