They're not romantically together (but they are together). But I say, nay to the haters. Ferdi really is one of the best MLs. The novel does a great job of building their growth and (platonic) relationship, and it makes sense in-universe. He was ranked 2nd on konorano hall of fame, and their ship is one of the most popular for legit reasons.
(I also cried buckets during many of his scenes).
I think if you finished the series and still don't like him, then there's nothing I can say,---but if you didn't and simply dropped it without understanding how it came to be, it's just your loss really.
