(this plot is not my idea, i got it from pinterest)

Person A is important - royalty, in fact. Person B is their guard, stationed around Person A at all times. 

"would it kill you to relax?" Person A teased.

"probably," Person B replied. "likely it would kill you, too. thats the point."

A smile flashed across the royal's face. "I'll risk it," they said, and held out a hand. "dance with me."
