Here is another official MTV by Frenesi (フレネシ). Some additional information added by me: メルヘン is a German word "Märchen" meaning "A folktale or fairy story". I think the more you know, the more you would appreciate the dreamy feeling the singer tries to create from her MTV. But also note that if one day you see someone in real wearing a blue dress trying to dip herself into the sea, it may seem scary instead of romantic as depicted by the MV ^_^.
