“Nice to meet you, I’m Yoon Hwayoung.” The man, more beautiful than a woman, smiled like a flower. Gyuwon, his bodyguard, flushed up to his ears with his head bowed. Nearly two meters tall, lean muscles, bronze skin, tall nose, pronounced cupid’s bow, thick eyebrows, and narrow eyes… This shy man’s appearance was too hideous despite being a bodyguard. Born with an athletic physique and senses, he made a living as a mercenary, but stopped because had such a complex that he planned on getting plastic surgery. Compared to him, Hwayoung was beautiful. With an amazingly beautiful face, fantastic body, and a well-paid job, he was the third son of the Yoon Group, a nationwide gang syndicate. He was being stalked for his exquisite charm. The Yoon Group hires Gyuwon to protect their beloved, youngest family member and reluctantly welcomes him, but Hwayoung’s eyes immediately shone. To Hwayoung who wanted to raise a big, strong, pretty cat, Gyuwon was the ideal man he had been looking for. One day, he followed Hwayoung into a gay, exclusive SM club, “DUNGEON,” while guarding him. “Do you know what I’m best at? Recognizing masochists. Must be instinctual.” Hwayoung looked at Gyuwon with a kind but cruel smile. Seeing at a glance that Gyuwon was an SMer with an inclination for being a gay sub, Hwayoung suggested that they be play partners… Gyuwon realized that the ideal type he’d always wanted was right in front of him, and felt that he would unconditionally obey Hwayoung. He weakly resisted, but when Hwayoung’s hand touched him, a groan escaped his throat. “Your crying voice is really lovely, Gyuwon.” Gyuwon’s back felt sweetly numb. The oncoming pain from was just a prelude to sweet pleasure.
