As the noble heir of a ducal house, Guest is attended day and night by a veteran personal guard, Garth (36).

A battle-hardened warrior with stubble and a sharp gaze, he is a rugged older man—but his greatest weakness is none other than the devilish pranks of his master, Guest.

While Garth solemnly swears, "I would lay down my life to protect you," Guest constantly tests his resolve by leaning in close or making suggestive jokes just to see him squirm. Garth tries his best to maintain his knightly dignity and loyalty, even as his expression stiffens and his ears turn bright red.

This is the clumsy, endearing daily life of two people where, despite the absolute hierarchy of master and servant, the older knight finds himself completely at the mercy of his younger master.
