Uzuki Shimamura is an ordinary girl who dreams of being an idol, so she goes to a special training school. One day, a producer for 346 Production shows up with the news that she’s one of three girls chosen for the Cinderella Project, even though she didn’t pass the audition the first time around. Uzuki is thrilled, but the project can’t start until the other two members are picked... The producer scouts Rin Shibuya, who he has in mind for the second opening. However, Rin isn’t interested in becoming an idol and turns him down flat...

Producer fails to chase after Mio when she runs out of the office. This makes Rin and the other project members distrust Producer's attitude and what he means to do on his own. Then Rin leaves the project too, and it looks like the whole thing may fall apart. Producer pays a visit to Uzuki, who had the misfortune of catching a cold at this critical time, but her smile and unflagging dream of becoming an idol strengthens Producer's resolve to bring Mio and Rin back into the fold.

Meanwhile, the other members hear about how Producer became cowardly in the way he interacts with the idols after a past incident...

It's been a month since the idol festival and the 346 Production Cinderella Project idols are expanding the scope of their activities and grow one step at a time. It's smooth sailing for Producer until a suspicious figure seems to follow him wherever he goes. Does Producer have a stalker!? In between jobs, the idols take turns guarding him.

And then a woman who was working abroad for a company affiliated with 346 Production returns to Tokyo to take charge of the company's idol division. But what startling new policy does Executive Director Mishiro announce!
