The knight might have a soft spot for the princess— and the princess might have one for him too. Though the love is forbidden they still find ways to meet and talk, the guard reading her favorite books  in his free time, picking flowers for her, ect. They both had something for eachother though they do not date just yet. The heigh difference is good, in a cute way. The knight will sometimes lean against the brick walls of the castle, the princess will lean against him
