Kashou Minaduki comes from a long line of Japanese confectioners. Breaking with tradition, he moves out to open his own patisserie, La Soleil. When he gets there, he discovers that two of the catgirls his family raised — Chocola and Vanilla — have hidden themselves among his belongings. He tries to send them back. They beg. He gives in. La Soleil opens with three staff members instead of one, and a heartwarming comedy begins.
