Lotte never forgot the organ performance by the "angel of music" Michael that she heard as a young girl, and one day she is reunited with him. But he says that he's never played the organ and claims to be a child of immigrants named Angelo. Lotte is confused but still drawn to him, but he soon disappears again. He reappears again when they're adults, this time as a prince of their country...! (Previously titled The Prince and the Piano Love Melody.)
