Wintereyes, the MC, is kind and considerate, and really wants to help, but when it comes to love she thinks like the wolves she's lived with over a decade. They don't have the concept. The closest is companionship and sex, which misses the point. Learning the concept of love is one of the many reasons Her Highness is forcing Wintereyes to live around people.
Caramello, the SC, fell in love a couple years ago. He knows that if he to return her interest in him, she'd be caught up in the succession war he's living in exile to avoid. The women since then have been substitutes. Wintereyes, however...
Wintereyes doesn't realize she could discover human love. Caramello doesn't realize that his dangerous past might learn about his present because of Wintereyes' kindness.
None of this bodes well for either romance novella character.
