After Divorce, Four Vampire Kings Chasing Me - Episode 3

A woman named Luna plans a romantic anniversary setup, but her husband Caesar ignores her, saying he's tired. She then overhears him cheating with another woman in the next room, who asks Caesar who is better. Caesar calls Luna a 'bitch' and says she is depressing and boring. Luna confronts him, reminding him of the sacred vow he made to perish in the sun if he ever betrayed her. Devastated, Luna reflects on the five years she wasted for him, realizing she became a joke. She then asks a person named Shirley to help her get revenge, swearing to make Caesar lose everything and burn in the sun as per his own vow.
