Cheerful middle-schooler Miku lives on a mountain farm with her grandpa, where they keep a large number of animals. When Aruga- a senpai at Miku's school- concocts a plan to help some local stray animals that are causing a nuisance, fellow animal lover Miku seems like a natural choice to help out. As the two of them become closer, Miku finds herself falling in love... but will dense Aruga ever figure it out?
