I mustn't fall for him, I'm only the king's fake fiancée... One night, while visiting the country of Santara in search of her brother, Regan was kidnapped by Jaeger, who claimed to be the king of the country. Furious that her brother had stolen his soon-to-be-married sister away from him, Jaeger believed that by detaining Regan in the royal palace, the two would return. I will not give in to that arrogant man! Regan sent out an unsupervised message on social media to announce her safety. However, it became the topic of conversation all over the world and created a diplomatic problem for the country, forcing Regan to be Jaeger's fiancée for four days!
