Toro Hazumi has opened the baked sweets specialty store of his dreams. However, he is devastatingly bad at serving customers! Customers who happen to visit him are scared of him and run away, making it difficult to run the business. One day, just before the store is about to go under, a high school girl with a mysterious atmosphere, Mikuru, appears. She is not afraid to talk to Toro, and her enthusiasm for baked sweets, which he had almost given up on, lights up in Toro's heart once again.
