Arans, who had the best chance of taking the throne, was stabbed in the back by his most trusted subordinate, Volek, during the election campaign, and he was reduced from a high-ranking lord to Volek's concubine. However, Volek's betrayal was actually due to hypnosis by someone with ulterior motives, which magnified his desires and indulged his own means. But when he woke up, he found that he had hurt the person he loved the most and pulled him down from the altar with his own hands. In order to win back his lover, he begins to "chase his wife to the crematorium".

Note: "Chase a wife to the crematorium" is an idiom meaning that someone who had once treated another badly before subsequently falling in love with them now has to endure all kinds of hardships in order to win them over.
