I Married the Dying Dragon KingEpisode 18

Sold by her fiancé to a dying king, mute Sheila expects death. Instead, the cursed Dragon King Bane offers her escape—if she speaks. Her first word saves him. It nearly destroys her. Now his queen, bound to a man who commands fire yet touches her with unbearable tenderness, she learns every word rewrites reality and drains her life. When Bane falls, Sheila must choose: stay silent and watch him die, or speak—and sacrifice everything.
