Sueños y caramelos (2005)

Sofia's grandfather is the head security guard at a huge department store, "El Gran Almacen". At night, while her grandfather guards the store, Sofia uses her imagination to turn the department store into a world of fantasy and dreams. She decides to tell her friends about this new world, and she and her friends have many adventures there. She meets a new boy, Juan, whom she believes is a poor orphan--but in fact he's the son of Mauricio, the department store's owner, and his biggest fear is that he'll lose her friendship forever if and when she discovers his true identity.
