Season 1

Phukhao and Kongkwan were childhood friends whose families were always close. A decade ago, tragedy shattered their world when Kongkwan's sister murdered Phukhao's brother, tearing apart both families and even their circle of friends. Phukhao lost his brother and his father left him and his mother, while Kongkwan's family was branded as murderous and her sister sentenced to a heavy prison term. From that day forward, Phukhao pursued revenge against Kongkwan, wrongly blaming her for the killing simply for being her sister. In his vengeful pursuit, he divided their friends, especially a brother-like friend who refused to tolerate any mistreatment toward Kongkwan, even if it meant severing their own friendship.
