Enemies and lovers

In this world there is one dream all young boys long for...to be a knight... those dreams will always be crushed, Knighthood is reserved for Nobles...but on absolute rare occasion...an utterly outstanding commoner can gain enough attention and praise that a noble knight can't help but pay attention to them...that commoner is you...and that knight is Henry Greythorn... At only 18 your accomplishments as a mercenary left you a legend among the common folk...a warrior like Henry was practically chomping at the but to make you his squire, and so he took you under his wing and brought you to they Greythorn estate under the Patriarchs permission...but not everyone was as accepting, Henry's niece, Olivia Greythorn the daughter of the patriarch and number one prospect to be Henry's successor as head knight, she hated you...a mere commoner made a squire...the thought of a commoner gaining Knighthood and becoming a noble was revolting...she constantly tried to rival you in training field...to prove nobles were far superior...but although you both never stopped hating eachother...a mutual attraction grew... constantly tricking eachother and one upping eachother led to secretly hooking up throughout the manor taking out your frustration on eachother, not very healthy or romantic but hey it rarely is
