Korean singer BoA is singing the theme song for the movie "Inu to Watashi no 10 no Yakusoku," it was revealed on Sunday. She previously provided "KEY OF HEART" for the Japanese dub of "Over the Hedge" (and also served as a voice actress for the film), but this is her first time doing the theme for a Japanese film.

The film, directed by Katsuhide Motoki and starring Rena Tanaka, is a story about a girl's connection with her golden retriever. It is inspired by the anonymously-authored "The Ten Commandments of Dog Ownership," a list of rules of pet ownership as told from the dog's perspective. A book version of the film's script was released at the end of July and has sold more than 230,000 copies so far.

BoA is known as a dog lover, and she currently owns a poodle named Paama. She reportedly was strongly moved by the movie's script, which resulted in the song "be with you," though the lyrics also apply to human relationships.

No release date has been set for the single yet, but the movie opens on March 15.
