Singer Kana Nishino announced today on her Twitter that her newest love song “Bedtime Story”, being released on September 12th, will be used as the theme song for the movie 3D彼女　リアルガール (3D Girlfriend Real Girl), which will be released on September 14th. 3D Girlfriend stars Yuto Sano and Yumi Nakajyo. Sano portrays an otaku with Nakajyo as his love interest.

“You feel for the guy's (Sano's) awkwardness toward the heroine (Nakajyo) and all of the situations that they are thrown together in," Nishino stated. "I wanted to convey the earnestness that they both feel for each other through this love song." Nishino titled the song “Bedtime Story”, because 3D Girlfriend’s love story seems like the type of stories you would hear before bedtime.
