Of all the many breeds of musician out there, few are as stubbornly uncinematic as acoustic singer-songwriters. Forget flamboyance, creative excess, clashing egos and all the other qualities that tend to attract filmmakers to the music industry in the first place. The average singer-songwriter gig is closer to a poetry reading than a rock show and is equally hard to dramatize.
Haru (Mugi Kadowaki) is the archetypal emotionally inarticulate artist: a dowdy loner who uses her songs to express the feelings she usually keeps veiled behind a facade of indifference. When she spots Leo (Nana Komatsu) at the industrial laundry where they both work, she's immediately drawn to her and suggests that they try playing together.
Impulsive and prone to self-destructive behavior, Leo becomes a muse and object of unrequited affection as the pair start performing under the cutesy portmanteau Haruleo. Things get more complicated when they graduate from busking on the street and decide to find themselves a roadie — a questionable investment for an unsigned duo with only a pair of acoustic guitars to lug around, but never mind.
