Spellcasters and fairies: can they be friends

I just made a Spellcaster and Fairy in CAS, teens and dating from the get-go. Half the interactions are fine, half of them (even if they previously liked it before) give them a negative hit. They can be romantic easily, but friendly is super hit or miss! They generated in the game with almost zero friendship despite being set as ‘partners,’ and fairly little romance bar. Very annoying and I hope we can fix this with a mod! Weird how some people seem to have no issues with it, though.
