The 'water king' is actually a woman, who is still bitter about a man in her past (water-girl's ancestor) who married someone else. She isn't happy about water-girl being rejected, and resorts to petty pranks. Also, somewhere along the way, MC makes friends with the wind king - which only makes things worse because the water 'king' and him both like each other. Now seriously jealous, the water 'king' tries to destroy the kingdom or kill MC and the prince, but is stopped in time. The wind king, who is a cross-dresser, dresses up as man for once and finally confesses to the water 'king'.
