Pretty sure it'll be season 2 or 3, it's a slow burn and season 2 was to be confirmed that it'll have romantic aspects. I don't know how long the novel is so it may be season 2 or 3 (if there is a season 3)
I know MC wants the best for the prince and that his mission is to undo the love spell and actually have the girl fall in love with Alec. But the fact that he cannot stop Alec from hooking up with him is already proof that he is already attached to the guy
