Synopsis：Kwon Jaesin has spent his life as a notorious fixer in the criminal underworld. To buy the island where he and his found family live, he strikes a deal with Chairman Lee — who sets one condition: marry his spoiled granddaughter, Lee Arin. To achieve his goal, Jaesin reinvents himself from shadowy criminal to upstanding, dependable man. True to his word, he rushes into a marriage with Arin — Seoul's most infamous troublemaker — and sets his plan in motion: tame his new wife. Arin despises Jaesin for being charming in public while speaking down to her and pushing her around in private, and desperately tries to break free. But little by little, she finds herself drawn to the dangerously attractive man she married.
