I recommend My Dragon King is Too Gentle to you. This novel tells the story of the heroine, Goxin, who met the Dragon King again to find the answer after becoming the Dragon King's wife for a thousand years. The heroine had been hurt by the Dragon King because of a misunderstanding, but her love for him had not changed. She had been waiting for a thousand years to reunite with the Dragon King. I hope you like my recommendation. Muah ~
