Can you hear my voice from the heart?

Miku Maekawa and Riina Tada are going to make their debut as the Cinderella Project's final unit. However, Miku aims to be a cute, cat-eared idol, while Riina's goal is to become a cool rock idol. The two are like oil and water, and both are strongly opposed to the unit idea. But when their participation in the units-only summer festival is on the line, they make an effort to get on the same wavelength, starting with becoming roommates!
