Also, seeing the CP's POV we see MC's father was highly respected for his ability as knight, and even got to teach him a thing or two.
So MC's plan to avoid his attention was doomed from the beginning. Even his 'novel' interest in her brother could have been sparked by their father's reputation. Heh. And now she delibetarily played fool in front of him and is going to be called out.
Damn, that is delicious
