The Cool CEO's Personal Bodyguard

He is a bodyguard, but also a battle-hardened king hidden from the world. The mention of his name fills his enemies with fear, and everyone who has witnessed his prowess has turned to dust. Yet at home, his aloof CEO wife is always misunderstanding him, her best friend keeps trying to push him into the abyss, and his mischievous twin sisters-in-law constantly set challenges for him. What gives him the biggest headache is that his despicable master keeps introducing him to beautiful senior female disciples. His life is like a surging river, never short of turmoil.
