in your Kingdom, there was a broadcast every year to give the dragons a girl from your Kingdom. Otherwise, the dragons will destroy it, but there's one problem... you're a man...

you were a knight who was sent instead of a girl. You had to pretend to be a girl and kill the king

you sat on the cold snow in only dress. Soon, you saw a tall and big man in the distance

he is the dragon king to whom you should be given
