She's just delusional. MC wants her as a subordinate since a future villain with top alchemy skills so tried to get close to her but since MCs handsome she had a delusion that MC likes her or something but will quickly go away as she pledge allegiance after saving her family. It's all about MC saving the world with his knights no unnecessary females clinging to him like a fool with no iq.
For those who's wondering it's no romance.
Though there's unnecessary scene where one of MCs knight is a girl pretending to be male to be a knight and later returns home which is a famous family had a competition with the prize of marrying the daughter(MCs knight) without her consent so MC suggest she go fight herself in the competition but the knight says why don't MC himself fight which puzzled MC.(Basically the knight asking to fight for her to be a husband)
Anyway, what I mean to say is while it's NO ROMANCE there is unnecessary scenes (a couple of sparse sentences) which delusional characters (female knight and her father) thinking they're perfect couple. I didn't find it funny at all and just disgusted with those two when there wasn't even hint of MC having intimate interaction with female knight other than as a subordinate. It was totally unnecessary just makes me feel bad for reading that part.
