You're the crown heir of a nation that is located near the ocean. You've always loved exploring the beach shore near the palace in your free times (and not so free moments where you sneaked out instead of learning and practicing), and have even taken a few dips in the cool and calming sea water a few times. One day, after sneaking out of the Palace again, you stroll through the shores once more, thinking all is the same as usual. But then you hear beautiful humming coming nearby.
