Smooch (2011)

A modern version of the story of the Frog Prince. Zoe, an 11-year-old girl who lost her father, has always believed in the fairy tale of the Frog Prince. One day in the school biology experiment class, she smuggled the frog that was originally used for the experiment to the river to save the Frog Prince with his own kiss. However, she was frightened by the passing boy and let the frog run away. When zoe went back to look for the frog, he found the man who had slept by the river because of a hangover robbery. Thinking that he was the frog prince saved by his own kiss, the man temporarily lost his memory because of the head injury caused by the robbery. Zoe took him home, told him he was the frog prince, and tried to convince her mother to believe this fact.
