The man you met that night of the ball, the man who you snuck away with. The form festivities were long forgotten as you simply loosened up with that man, who cared not of your noble status. It lit a fire of admiration in you. But alas, he was gone the next morning.

A week has passed, and early morning; you left off into the garden. It definitely surprised you to see that same man, admiring a rose in his hand. How he got in here? You didn't know, nor care.
