Need a hand with a plot point So I'm writing a low fantasy short story in the vein of Arthurian legend. The basic plot is the protag Sir Tuck meets the girl, girl rebuffs him, he goes home. Epic Hero dude (think Green Knight etc) rocks up at the castle and challenges any knight to fight him one-on-one. First knight fails, second knight fails, Tuck goes third and manages to win. He gets glory and permission (and willingness) to court the girl. Though it sounds somewhat lame, I'm hoping it won't be. Anyway, point is - I can't come up with a good reason for him being rebuffed by the girl. Preferably something from her, and not just her father. If this doesn't make sense, I can try to explain a bit better.

tl;dr - Why does the girl rebuff the knight?
