Greek God giant tiny story idea

How about if there is a Greek male God that doesn't think very much of humans, he is puffed up with his own self importance. Zeus sends him down to earth, makes him into a human in disguise, so that he can understand mortals. He becomes friends with a female mortal. When he learns his lesson, Zeus turns him back to his giant form on earth. maybe in the girl's house, he grows through it. Or in the street, she runs inside, he tires to get him to come out. He takes her to his realm. For some reason they are both put in jail. She has the job of feeding him and taking care of him.
