He chose his adopted sister，I chose my Alpha King - Episode 1

Introduction: "Serena of the Mooncrown Tribe once saved Adrian, helped rise him to Chief Enforcer, and bonded with him despite her father’s objections. After their bonding, Adrian distanced himself from her, claiming old injuries. She soon discovered his heart belonged to his adopted sister, Ivy. Serena resolved to break their bond and travel to the Nightveil Tribe to mate with their Alpha. Before her departure, Ivy destroyed the wolf-bone necklace left by Serena’s mother and harmed her. Adrian took Ivy’s side and imprisoned Serena on the estate. Once released, Serena gathered medical evidence of her injuries, formally accused Adrian before the Council Chamber, and boarded the Nightveil Tribe’s wedding carriage. It was only after the bond-breaking document took effect and his position was suspended that Adrian spotted Serena inside the carriage, realizing she was truly gone for good."
