I don't particularly like Sylph but she made Eliza happy while MC was away and now Eliza treats her like a sister, so I wouldn't turn her away. The rest though ... I kinda feel like they were forced on us, and then we had to say more than once we weren't interested before we were "locked" so it's kinda like people who keep hitting on you, pretty blatantly after you've told them repeatedly that you're not interested. After awhile it goes beyond awkward and just destroys the possibility of any kind of relationship. Also, as I've said - I'm pretty mission focused. I want to get revenge, and then I want to keep Eliza safe and it seems to be the best way to do that is to go somewhere that no one knows who she is (or who MC is). Then we can be known locally as farmers and the people you go to if you have a problem with wolves, or goblins or bandits etc. Basically complete the three tasks before you and then disappear.
