Both have a sweet, innocent supernatural female lead (that at one point walks around barefoot with a white dress!) that adapts to the human world. Also both heroines must protect the lives of the heroes for a certain amount of time due to different reasons linked to their powers, and both heroes could die without this bond. Both male leads are also trying to pursue an artistic career: in MGIAG, he wants to become an actor, and in SA, he is a photographer. Also, both dramas have a darker supernatural character that has a soft spot for the female lead.
