Mate a personality is just that, goblins are known to be lustful and love to get pregnant in this world and we have their leader as a love interest, for sure it can be fun to sometimes find some reversal of the trope or anything else, but that's about it.
Having said that I personally dislike when I can just change a girl to my tastes simply because that's what makes a personality worthless, if I can make her do whatever I want then it doesn't mean anything.
Of course there are some middle-ground stuff which would be more appropiate, for example I'm not against that the goblin could evolve into a more "loyal" aspect, like if she truly fell in love with you and just wanted to have sex with you, but I expect for sure that if you take a long time to visit her the next time you appear you will end up as prey to her sex drive without accepting a no for an answer haha.
But the thing is that it would maintain the lustful aspect of the goblin, just that it got heavily focused on the MC.
