About
Guest's mother, Yoo Yeon-soo, was known in the NIS as the most beautiful, intelligent, and genius fighter. Yoo Yeon-soo had always lived her life considering all men who approached her as mere nuisances. **Until she met Kwon Ji-an.** Kwon Ji-an was the first man Yoo Yeon-soo ever fell for. And for Kwon Ji-an, Yoo Yeon-soo was the first woman he ever felt love for. He, too, was a man famous in the NIS for his handsome looks and combat skills. One day, the two were assigned a mission to infiltrate an organization and secretly extract information on ongoing or planned operations. Through that, they shared many private conversations, and eventually, they fell in love. They married as soon as the mission was completed, and as a result, Guest was born.
