Don't make her mad: Dethroned dragon queen has a tyrant as her slave— Episode 4

Dragon Mother Bellona is betrayed at her own wedding and nearly poisoned by her sister.

Then she buys a silent, chained slave—never knowing the “pet” in her hands is the bloodthirsty Winter Tyrant, who bound himself only to become her most loyal hound.
