The story in short: The princess was kidnapped by a dragon. A knight rescues her and then marries her. They will have a child with a normal name. This is worth mentioning because all the characters have idiotic names.
So the original song is about a hero's adventure to save the princess captured by a dragon. The catch is that the characters' names are super long and they always use their full names. In the 周深 cover, each character + narrator use a different voice so it's extra fun to listen to.
WOW!! That was a fun song and the switching from man voice and cute voice is smooth! And everything got faster in the end haha ~ you deserve that breath of relief in the end~!! ^o^
