Unfortunately, his assignment involves dealing with a naive royal whom he finds bothersome for constantly following and proposing to him. Despite his reluctance, the ninja is captivated by her charisma and gives in to her needs whenever she asks. To put an end to their unprofessional relationship, the company leaders are employing secretive methods. This is a modernized version of a classic love story involving a boss and a subordinate.
