Since there's this prince lance and knight keith au going on, i give you this heartbreaking one:

Lance and Keith have been in love since they were children, lance being the small prince and keith the son of the right hand man of the current king.

They grew up to be fine men, lance became the one next in throne and keith is now his personal knight. Keith has been with lance all through this time and he believes that he is destined to protect lance, his king.

He stands beside him through and through.

Keith stood there as lance's father arranged a marriage alliance with another kingdom. He watched lance with pain as he knows that lance doesnt want this either. Keith watched lance dance with the said princess on the dance floor. Held her hand, smiled at her,

whispered words to each other as if they were the only people in the room.

god... Keith wished it was him. No matter how hurt he feels at the sight of the one he loves holding another, he didnt dare to look away. How could he?

Keith was a knight first, a lover second.
