People are so hard on Ignis 😛
I mean it is highly hinted that he is a sociopath, but at this point in time he can still come out as a decent person (depending on what the author will do next).
It was shown that he was truly angry seeing hero in such a shabby house in previous chapters, which means that to some degree he cares for people like good monarch should. He don't want to lose talented people and tries to coax them to his side, which also is reasonable for a good ruler.
Unfortunately, the methods he is using are questionable. He is quite manipulative and cunning. He is doing great use of all information he has gathered, to achieve his goal, but in the end, he did not really force our FL - he gave her a choice (making sure beforehand that his offer will really look as best possible action in her case). He is cunning, but I think it is still too early to deem him as a full-fledged villain - I mean I suppose that the story will go this way, but I think the author left some space to make a reasonable twist that he is not exactly a villain.
Can't wait to see how the story will unfold
