Arashi Sakamoto is a man belonging to music. Mixing and composing is his specialty and his new business of producing music artists’ new albums is taking ground. Topaz Kissinger, his little sister’s best friend, is a woman he never expected to get to know beyond a few words at a time. When Topaz calls in need of a rescue from a bad situation Arashi responds. That one night changes everything. But with two hearts in flux can music bring these two into harmony? Or will a recently broken heart shatter before it can mend?
