The Prince and his Bodyguard

A cold, secret mafia king and a spoiled, ribbon-loving prince fall in love at first sight. Hired as a bodyguard by Ziyu's doting parents, Tianxuning finds himself consumed by the clingy, beautiful young man who claims his lap-and eventually his heart.
Through jealousy, misunderstandings, and a near-tragic separation, they forge an unbreakable bond, welcoming twins and later a fiercely possessive third child.
Set against a backdrop of decadent wealth, possessive children, and endless devotion, this is the story of a ruthless killer who kneels only for his princess, and the pretty boy who rules his world with ribbons, tantrums, and an ocean of love.
